[Plugin: PhotoSmash Galleries] Thickbox and custom fields / linking to thickbox

Hey Photosmash users:

How do you use the Thickbox for displaying individual photos, BUT bring your custom fields into it?

Right now, I have custom fields in the gallery display, but cannot find out how to modify any layouts that allow the thickbox to display the custom fields.

Secondly, anyone know how one can link to a thickbox display of an image, rather than linking to the JPG?

Thanks!
