Body Field Text Becomes Thickbox Caption

Hello,

I am setting up an image gallery using CCK and Views, as described here. This results in a Thickbox view if the gallery thumbnail is clicked, and shows the full node when the title is clicked (in case users don't have Javascript enabled).

I've renamed the body field as "caption" so the client can enter captions for the photos there when uploading the images. But when users are looking at the images in the Thickbox view, the captions don't show up. I know an optional title field can be enabled and they could paste in their caption there as well. In addition to being a clumsy extra step, I can't get it to work after checking "Enable custom title text".

This trouble prompted me to think of a better solution anyway: Just have Thickbox automatically use the body text as the image's caption. I've looked all over the forums, and seen similar threads, but nothing I've found addresses this question exactly. I'd really appreciate hearing if this is possible and how it could be done.

Thanks,

Jim
