Add Thumbnail and subtitle to exhibit section titles links

I am trying to add a thumbnail a 3 word description to each of the section titles under an exhibit built in exhibit builder.

Where is this loop code located so I can add to it? or is there an easier way I haven't found yet?

Thanks

There currently is no way to do this. You might try adding an img tag into the section description, though I'm not certain that will work.

There isn't really anything you can add to the loop because there is no current way to link items with sections.

In the europeana exhibition about Art nouveau, they do something like the one you need:

But I guess they don't link section thumbnails with omeka objects.
