Add redirect to mobile-only photo URL when in desktop UI

This URL is only used in the mobile UI, but when somebody then copies
the link and sends it to somebody on the desktop UI, they don't see
anything. So lets just redirect to the post containing the photo, so
there is at least something to show.

If there is no linked post, just redirect to the image instead.

Fixes #8352
