Thumbnail image for random/featured exhibit lists


Does anyone know of a good method for extracting an image from each exhibit so that it can be used in a list of recent/featured exhibits?

This seems tricky.

One way might be to add an option to the Exhibit Builder admin interface so that users may choose the image (kind of like the WordPress post_thumbnail() function).

Another might be to somehow figure out the first image being used (if any) in a given exhibit.

I think both would require a fallback to either no image or a default image.

Any ideas on how to proceed?
