I'm on Chrome. Perhaps it's supposed to not show in full? It looks like a macro view of the section.I like this idea a lot, passing it along to the dev team to see how hard this is to make for y'all.
The gallery and showcase features are great. The Showcase if for a single post, and the gallery can be a wider assortment of albums including videos and audio files. Unfortunately it looks like that post is an error of the uploader, so you may want to poke them to get that sorted
What mobile browser are you using here? I have yet to see this issue on safari, chrome, firefox, or even the Tapatalk app.
Hope to help you resolve this
I don't see the full description anywhere else though.
(sidenote, uploading this screen shot was very easy )
