sbillard.. just reread your reply to my post above... I have never never set an password for my site.. should be there at www.bertsimons.nl
Sorry, but I discovered another wrong behavior concerning this topic.
I modified the image.php a little. Instead of using the function getProtectedImageURL() to show up the image, I did include getAlbumLinkURL() to go back to the album/subalbum. But the link generated by getAlbumLinkURL() leads not back to the related subalbum. In case of the above mentioned example the link to the subalbum looks like this: http://www.synnatschke.com/gallery/north-america/usa/arizona/misc/page/2
The correct one should be this: http://www.synnatschke.com/gallery/north-america/usa/arizona/misc/
I am afraid your "bug fix" causes another error. Please follow this link: http://www.synnatschke.com/gallery/north-america/usa/arizona/coyote-buttes-north/the-sky-is-the-limit.jpg.html
