Hi,

New to Zenphoto and migrating users from Gallery 1. I love the script, but the one thing that seems to be m,issing is captions for the thumbnails in albums.

Is there any way to do this?

All image objects have Descriptions and Titles, so if what you are saying is that [whatever unmentioned] theme you are using does not display such information with the thumbnail, then the fix is to add that feature to the theme.

You should review the articles on http://www.zenphoto.org/news/category/theming-templating for more information.
