Hi,
I want to add a couple of images to my PEP3 gallery.
I tried copying them to the gallery folders where all the other images are located, but that would've been too easy - PEP3 doesn't recognize/show any new images.

So I tried exporting the gallery to a GEF file (which seems to be a normal ZIP format).
I extracted the file, added some new images and then zipped everything again.
I replaced the .zip extension with .gef and tried to import (merge) the updated gallery file into PEP3.
Unfortunately I'm always getting an error:
"The selected GEF file is either invalid or corrupt and cannot be imported."

I even get this when unzipping the exported gallery and re-zipping it without modifying any of the files.

Does anyone know why PEP3 is so picky about the file?
What am I missing?
