Captions on image

I have added image captions module. See http://drupal.org/project/image_caption for some details. There is a remaining piece of configuration that I need to do to make it easily usable from the Rich Text editor, but I don't know where to make the change (still looking).

There is a screen shot of an example and some instructions on how to theme the caption, e.g. smaller type and probably a background tint.
