i am testing a lot with the gallery for the moment and found three issues:
1. extra fields seem to be imported right to db but not shown on folder or image view yet.
2. "More thumbnails" ajax-loader not working correctly.
e.g i have a gallery with 7 pics and set "Thumbnails per page" to 6 but all 7 images are loaded instead and the "More thumbnails"-link appears at the bottom of the folder-view until all thumbs of the folder were loaded twice. (14 pics)
