Comment (by Fab1en):

 I see two directions to make this happen :
 1. Store the caption of images is the gallery directly in the gallery
 shortcode. That is not possible today (because HTML is not allowed in
 shortcode attributes) but it could be possible with the future shortcode
 format that will allow to split shortcode content into several parts, each
 part being an image caption.
 2. Store the caption in a postmeta field, linking it to the gallery id.
 This is easier to achieve but will not solve the previewing issue.
