Hi,
I have zenphoto setup on my server and just trying to design the main page (to then mod a theme to use the menu).
However.. I have noticed that only the default theme works, all the others do not have the CSS applied to them.
In fact looking at the generated html the default theme produces

while the others produce

Are you sure you're using the newest version of ZenPhoto? I believe that Tristan got rid of most of those shortcut tags.

using whatever is on the download link like 3 days ago (had to re-unzip mess it up)
zenphoto-1.0.8.2.tar.gz

and yup all the themes (bar the default) have it.
Not too much of a concern the default (well maybe teh sterile) is all I need, need to mod it to merge in with my site (when site really exists)

Sorry, I was wrong. He got rid of all those tags in the core code, but not in the default themes.
