unexpected deleting of files in USB memory

I was checking out some photos on a USB memory stick. Then I started to do some editing of a photo in the Eye of Gnome software . I was cutting the photo with frames to make it smaller. The software seemed to be in some kind of error because I couldn't save the photo. Then I closed the software, and all of the photos in that folder and the other photofolders were deleted. It seemed to have happened in just a second. The weird thing is that everything else but the photos is still on the USB drive.

I've just used Ubuntu for a few days so I can't really figure out what to do. Are the photos recoverable? They seem to be gone when I try in a windows laptop as well. This is all the info I have as for now.
