I'm completely new to zenphoto but I have to say that I really, really like the idea of using this as a replacement to my gallery2 installation!

Now I'm looking for a good theme to adapt a bit myself. Are there any themes that are compatible with ZenPhoto 1.2 that support lightbox/slimbox/roebox out of the box (no pun intended) and are XHTML strict?
I don't think any of the standard themes supports a box variant? XHTML strict compliance or compatibility with ZenPhoto 1.2 seems to be an issue for all themes I find here?

(Perhaps I did not search well enough, feel free to say that to me)

We do not try to be XHTML strict compliant. Why is XHTML 1.0 Transitional not sufficient?

Thanks for your reply
I can settle with transitional as well, if I really need strict I'll convert it.
Any ideas on themes for ZenPhoto 1.2 that support *box?

Adding any *box is really easy, first we have thickbox already on board (jQuery is our standard lib), but any other *box derivat can be added the same way. Actually you only have to get a little familiar with our themes to add that (please visit our user guide section and the theming tutorial).
Also take a look in this thread about the slimbox (setup is the same for all boxes): http://www.zenphoto.org/support/topic.php?id=3382

Okay, that makes life easier. Thanks for your help, now I only need to look at the migration.
