Hi all, I know this is not what you are wishing for, but it is a workaround, and it's quite easy to do.

Here's a screenshot of a template with three images that have description segments between them (the arrangement can be configured in different ways):

You open the HTML Template Manager and select one you want to use; duplicate it; click to Edit it; then just add Formatted Text and Image components (check the box for Break After each image); then save it with a new name related to the item being auctioned.

Yes, it's a bit of a pain compared to just adding images directly to the Description box in the Lots window, but it's not that difficult. When the Lot is sold, you just delete that template or change its images and edit the wording in the Text components, rename it, and use it for a new auction.

P.S. I must confess I haven't even used this concept yet. I just tried it out tonight and am anxious to submit an auction this way.
