Tried this, but it doesn't work because of another ForbiddenAttribute
error :

  File ".../gallery/browser/folder.py", line 39, in getImages
    return sorted(result, key=lambda x: IGalleryPhoto(x).name)
  File ".../gallery/browser/folder.py", line 39, in <lambda>
    return sorted(result, key=lambda x: IGalleryPhoto(x).name)
ForbiddenAttribute: ('name', <gallery.photo.GalleryPhoto object at
0xa5bc46ac>)

As said before, 'IGalleryPhoto' (implemented by GalleryPhoto) is
provided in the "allowed_interface" attribute of my ZCML's view page
definition...
