Adding HTML to photo captions

[SamZ]

I use Coppermine to show images of paintings that are for sale in my friend's gallery.  I want to be able to list a price for each painting while viewing the intermediate image, and have that price be a link to purchasing information or possibly a shopping cart in the future.  The problem is, it doesn't look like I can publish HTML in the photo captions, so how do I accomplish this?

You can use bbcode - refer to the documentation for details. If that's not enough, search the board for the existing shopping cart solutions.
