Display image file name in Photo Viewer

JanetSilb_Spike

Hello community,

Usually I want to hide an image file name from a popup or in an app. However, within this particular Photo Viewer Instant App configuration, I would like the image file name to display. Each point has a sequence of photos by season, and are so named. It would be helpful if viewers could see the image file names but I haven't been able to find that option in configuring the Photo Viewer. 

Thanks for your help!

An additional note: I thought about adding a "Description" field but that would only allow for 1 description for each record/feature. However each feature has 12 photos so the descriptors have to be tied to the attachments, rather than to the feature.
