So far, I haven't been able to figure out why some of your albums work, but others do not - Tag1 and Tag2 are OK, but Tag3 is broken, and so on.
I think it may have to do with using quote marks in titles and comments, which is always dangerous. There are also HTML errors in your header and footer material, which could be causing problems. Also, I'm seeing <br /> tags in alt and title attributes, which isn't strictly legal. But I can't create a "broken" album, even when I introduce the same errors.
