A client cannot access my gallery/download.

There can be several reasons for this error:

1. Disabled cookies for you or your clients:

Make sure that cookies are activated in your browser and that your clients have also activated cookies for PicDrop. Access to password-protected areas is not possible without cookies. Alternatively, deactivate the password to allow your client access to the gallery.

2. Completely outdated browsers:

Some clients, especially in large corporations, unfortunately still use completely outdated browsers. The reason for this is usually strict security regulations from the IT department. They like to use "secure" old browsers instead of laboriously converting all computers in a company to newer, modern browsers. We try hard to get PicDrop to work on ancient browsers, but we can't guarantee it on browsers that are ten years old. If your client might have this problem, simply ask him to use another browser.

3. Very sharp security settings:

Large companies and corporations, especially in the banking, aviation and pharmaceutical sectors, extremely protect their employees' PCs from external dangers such as viruses or unknown websites with potential traps. This often means that only a handful of websites can be accessed. All other pages, whether news, football or image transfer pages, i.e. PicDrop, will then remain blocked or only function incompletely. Unfortunately, we have no influence on this. If your company or your client's company is affected, a discreet hint to the IT department will help to put PicDrop on the "Whitelist".

Bye bye, Plain Links! Hello, Custom Links!

With today's update (16.11.21), you can create individual "custom links" independently of the gallery name. Sharing new galleries via the previous "plain links" linked to the gallery names will no longer be possible. Existing galleries with active plain links can still be opened until December 15th. To increase the security of your galleries, we take a logical step here.

Read more about what you can and should do to ensure that your clients can still access their galleries in this article.

Plain links? What are Plain Links?

Plain Links are links that don't look like this:, but for example like this: 

In the security settings of your galleries you could choose between both variants. The Plain Link variant was used to get more readable URLs. However, for the last 4 years the second variant, the "secure link", is the default setting for all new PicDrop users.

So if you are part of the majority of our users who always use the "secure link" to share galleries, you can stop reading here. Nothing will change for you!

You are using Plain Links?

If you use Plain Links regularly or have used them in the past, please note that these plain links will STOP working as of Wednesday, December 15th. This also applies to links that have already been sent. If you currently sent out links to clients, you have 2 options:

  1. You can send a new (secure) link to your clients. Or … 

  2. You can create a new Custom Link for the gallery. 

Go to the gallery settings and edit the Custom Link according to your wishes. You can e.g. use the gallery name as before or enter a completely individual name. Please note, however, that this link is then again less secure than the randomly generated link. To increase security, we strongly advise you to always set a password as well.

The security of your data is important to us

At PicDrop we regularly take security precautions, check our application for improvement possibilities and implement them. In the security settings of each gallery we inform you that Plain Links are not as secure as the "secure links" and can be "guessed". Until now, we have relied more on your personal responsibility in deciding which link you choose and let all photographers decide for themselves what type of link you want to use for your galleries. In the future, we want to support you even more and hope that users will use this function much more consciously than before.

How can I still send pretty, more readable links?

Yes, the time of automatically generated links Plain Links is over - unless you consciously decide to keep using them. In this case you can now edit the address of the link by clicking into the address field and name it individually. This is a new option with a similar result: a readable text link. So you can still create nice URLs for galleries that should be public, for example. But now you are no longer locked into automatically using the name of the gallery as the link! This way you can make sure that a link you sent to your clients in the last days remains available after the change on December 15th.

I have a lot of plain links that need to remain accessible. What now?

Of course, we know that in some cases there are a lot of plain links that need to continue working under their old address. In cases where the number of links is too large to check the settings yourself, or where you do not have an exact overview, we are happy to help. Please contact us at so that we can work with you to convert your old plain link galleries to the new custom links. We are happy to help you!

The upcoming changes in a nutshell

  • You are using only secure links for your galleries? Everything stays as it is and there is nothing for you to do!

  • You have been using Plain Links for your galleries? As of December 15th your galleries will no longer be accessible via the Plain Link.

  • What do I have to do now? The easiest way is to send your clients the new randomly generated link to the gallery. Alternatively you can edit this link in the security settings of each gallery (and thus make the old link usable again). It's best to set a password for the gallery at the same time, if it doesn't have one yet.

I still have questions.

No problem! Write us at and we will be happy to answer all your questions.

Filtering selections on my hard disk/Lightroom/Capture One does not work.

This can have several causes.

Spaces in the file name
Lightroom, Windows Explorer, Apples Finder, etc. cannot filter out files that contain spaces. Before uploading, you should make sure that your file names consist only of letters, numbers, and underscores or hyphens.

Files renamed to PicDrop when uploading
Basically, the files on your hard disk must have the same file name as the files in your PicDrop Gallery and the selection you want to filter out locally. So you should make sure that e.g. Lightroom does not rename the files when uploading.

Missing fill zeros
If additional images are filtered out instead of your selection, this is often due to missing "fill zeros" in your file names. From the beginning, for example, if you filter to "File-2," Lightroom and Co will display all files that contain the "File-2" section in their names. Unfortunately, this section is also found in other file names such as "File-24". The result, both files (or even much, much more...) are displayed.

To solve this problem permanently, we recommend naming files from the memory card to the hard disk so that the trigger number always has at least 4 digits at the end of the file. Shorter digits before should always be filled with zeros. So "File-2" would become "File-0002" and the number is always and everywhere completely unique, even when filtering in Lightroom. For example, using this method, the "File-0002" file can no longer be part of the "File-0024" file name, as it was before.

This procedure helps you in many other programs besides Lightroom, including PicDrop.

Capture One
You may be using the wrong search in Capture One. Please use the search described here.

Exceeding the number of characters in the Explorer or Finder
The filter text in the Explorer can contain a maximum of 259 characters. The filter text in the Finder is limited to 2048 characters or 99 files.

Photo Mechanic

Photo Mechanic offers two different search tools. Please use the search via "Edit & Find..." in the menu to filter your selection. Here you will find the required settings for Photo Mechanic's search window.

My TIFFs look funny.

There can be several reasons for this. The most common error is that JPG compression was used instead of ZIP compression when saving the TIFF. This kind of compression is not 100% compatible with many image processing programs and also with PicDrop. We therefore recommend saving with ZIP compression. This method also has the advantage that, unlike JPG compression, it does not reduce the quality of your image data, but still effectively reduces the file size.

My upload in Firefox version 62 does not start or freezes

You are probably using an ad blocker. Please check your browser for installed browser plugins like:

  • Adblock
  • Adblock Plus
  • uBlock
  • uBlock Origin
  • etc...
Unfortunately, our tests and reports of users have repeatedly shown that ad blockers can severely hinder the upload. We are still trying to understand this behavior better, because PicDrop of course does not have any advertising. If such an ad blocker is installed on your computer, please deactivate the blocking permanently for the domain This can often be done with one click.

Then restart your browser. It should work now. If not, you can reach us at any time at

My upload is slow or aborts.

For problems with very slow uploads, aborts or incomplete uploads etc. we recommend the following procedure:

In the browser:

  1. Restart your browser and computer. Very often the problem has already been solved afterwards.

  2. Please try uploading in another browser. We recommend in this order: ChromeFirefox, and Safari. Is this working any better?

In Lightroom Classic

  1. Please try to change your FTP settings from FTP and port 21 to SFTP and port 22. If this is already the case with you, please try the other way round. In many cases, this should help.

General Information

Please check the speed of your internet connection. Unfortunately, it is still the case that even the fastest lines (DSL, cable, etc.) have a rapid download, but the upload speed is only a fraction of this speed. You can find out how this works for you in the contract details of your Internet provider or you can just test it. At you can test the speed of your line and send us the results of the test in case of further questions.

If you have the possibility to test another computer or to test your computer via another internet connection, we can also recommend this to detect the error.

  1. Please check the settings of your router, your possibly installed firewall, and possibly installed browser extensions. Does it work better after a short deactivation of firewall and extensions? (Attention: don't activate again!) If yes, please check the settings of your firewall in more detail. Uploading via a network cable instead of via slow WLAN is also optimal.

  1. Please remember, parallel downloads or streams (music, videos etc.) slow down the speed of your upload extremely!

None of these are helping.

In this case, it is very possible that your internet provider has blocked the FTP-Port (21). This is occasionally the case in public WLANs, in hotels and holiday homes, at airports etc... Or a bad Internet provider. Some providers want to prevent the misuse of "their" Internet connection, but unfortunately, also block serious services such as your upload.

An alternative?

Have you already looked for another internet connection or just tested it with friends, colleagues or neighbors?

If you have tried all of the above and your upload still doesn't work correctly, please send us an e-mail to Thank you!

The client login or naming the galleries does not work.

There can be several reasons for this error:

1. Deactivated cookies for you or your clients:
Make sure that cookies are activated in your browser and that your clients have also activated PicDrop cookies for third parties. Access to password-protected areas is not possible without cookies. Alternatively, deactivate the password to allow your client access to the gallery.

2. An outdated web integration on your server:
You are still using an old web integration. Please download and install the latest version of the web integration. You can find the download of the web integration again in your account settings and you can simply overwrite your old web integration.

3. Other installations on your server (Wordpress and Co.)
Probably other applications such as the popular Wordpress or Drupal, Joomla or a framework are running on your server or storage space. They often save certain addresses like etc.... If you or your client try to call PicDrop via your web integration, this application "kidnaps" the entered address and displays error messages instead of PicDrop. To eliminate or exclude these applications as error causes, please change your Wordpress or other programs on your server and exclude your PicDrop folder from their functional range. If you have detailed questions, please contact your programmer or system administrator or the manufacturer of the corresponding program to change this behavior.

The Lightroom upload does not work.

Do you see get the error message

"An internal error has occurred: ?:0: attempt to call field 'AgNetIO' (a nil value)"

this is probably because you still have the old macOS Mojave operating system installed on your computer, but you are using a current version of Lightroom.

The Lightroom plugin can only be used on macOS Mojave up to Lightroom version 10.2. Please update your computer to a newer operating system or downgrade to Lightroom 10.2 or older.


Do you see one of the following error messages?

Unable to upload because Lightroom cannot ascertain if the target destination exists.


“The specified FTP preset is incomplete and cannot be used.”

In most cases these messages are caused by incorrect login credentials or FTP settings. To eliminate these errors please follow this checklist step by step. Even if some of the steps seem trivial or funny to you.

  1. Make sure that you really entered as the server and not just

  2. Make sure you have entered your username correctly. You can find the username here.

  3. When exporting files from Lightroom, make sure you selected "PicDrop" in the "Target Server" section (at the bottom). Please read our installation instructions very, very carefully, as such important details can be quickly overlooked.

  4. Please change your password in your PicDrop account settings and then adjust the FTP settings in Lightroom. (Do not forget to save!) This option prevents typing and copying errors.

  5. Check if you use unusual special characters like "&" or similar in the gallery name. If so, please try it without this sign.

  6. Try to switch your connection from FTP (port 21) to SFTP (port 22), or vice versa if you already use SFTP. Please do not forget to save the settings.

  7. Make sure you are not using any form of firewall or programs such as "Little Snitch" that block your connection. Disable these for testing purposes to see if it works without them.

  8. Please test if another network/WLAN or a hotspot through your mobile phone is solving the problem, so you can be sure that it is not your network that is blocking the upload.

Still not working?

In this case, it is very likely that your ISP has blocked the FTP Port. This is occasionally the case in public WLANs, in hotels and holiday homes, at airports etc... Or a bad Internet provider. Some providers want to prevent the misuse of "their" Internet connection, but unfortunately also block serious services such as your upload. Please try SFTP and port 22 (see point 6).

An alternative?

Have you already looked for another internet connection or just tested it with friends, colleagues or neighbors? We also recommend that you upload via your browser. This cannot be blocked and thanks to our convenient drag & drop upload this should be very easy for you. If none of this works, just write us at and we'll see how we can help you.

Why aren't my file names completely displayed?

Within a gallery, PicDrop automatically scans your images for repetitive behavior in the file names. These name parts, which are always the same from file to file, are then hidden in the image overview. This ensures that only the relevant file numbers are displayed. Your gallery will be clearer and communication with your clients will be easier. Of course, the complete file name is always displayed in the large image view.

If you don't like the automatic file shortcut, you can simply disable it in your account settings.
