Can anyone tell me which themes have Lightbox, Slimbox, Truckbox, etc?

I tried doing a search but got too many "false positives" to make the search useful.

Thanks.

Also, I notice that the index.php file is linked to stylesheets for both Slimbox and Thickbox. Does this mean that their functionalities are built into Zenphoto??

Thickbox is included by default and used here and there on the admin and in some themes for displaying exif data. But the feature is not implemented for viewing images in the default themes. You can do that easily yourself as described on the Thickbox site itself. Also review our theming tutorial.
