I am adding in information associated with author and source, however this is not being displayed when published.
@mrkrndvs This is because the photo template doesn’t call these particular details even though they may be provided. I could see an occasional use for including them, particularly to give credit to a photo that was taken by someone else, while in practice most may not use this because they’re posting their own photos.
In the meanwhile, it may not be too tough to cut/paste bits of appropriate code from other templates to get these to display the way you want them when they exist. You can create a custom photo template named kind-photo.php and put it in a folder entitled kind_views in either your theme or (preferably) in your child theme so it isn’t overwritten on plugin update.
I do still wish there were a master template in the set (heavily commented and unused) that used every variation of data that could be displayed (or perhaps even calculated for display) so that non-programmers could attempt to more easily cut/paste templates to get them to do what they wanted.
