Gallery App refuses image upload

Using Gallery app, I have set up 2 albums. When I attempt to upload an image, it appears to work but nothing is in the album. The perch/resources folder has permissions 777. Inspecting the database table perch2_gallery_albums shows my 2 albums, but perch2_gallery_images is empty.

I have been using FancyBox, but not with Gallery - could there be a clash?
