You can easily move or copy pictures from their current gallery to another gallery in PicDrop.
This is a step by step guide on how to do this.
First select the pictures you want to move or copy. To do so, click on the blue plus sign that appears in the upper left corner of the image when hovering the mouse over it.
Pro tipp: You can also quickly select any number of images to copy or move from a saved selection or any filter set in the filter bar.
When you have selected all images, click on the Move / Copy images icon located in the export bar at the bottom of the screen.
In the opening menu you can now choose whether you want to move or copy the pictures. Select the desired target gallery in the list of your galleries or simply create a new gallery in the lower left corner.
Confirm your selected action with the button in the lower right corner and you will find the copied or moved pictures in your selected target gallery.
