Thanks designsimply, I just updated to the second update and still.. nothing.
These are the only plug-ins I'm using that have anything to do with the images:
- Add featured image to RSS feed 1.0 (inserts an image in the rss feed)
- Display All Image File Path (show path of all image sizes in admin)
De-activating all three, did not make any difference. But I appreciate you pointing to the theme as a possible solution.
SO, I went to look at my "mother" theme's stylesheet and found lots of definitions for .gallery, .singular-attachment, .hentry.format-gallery, .hentry.format-gallery
I'm not advanced enough to know how to get my child theme to ignore the mother theme's style sheet (just how over-write individual elements with my own). So I just ripped them all out of the mother theme's stylesheet (which I know is not the best way to go).
Anyway I broke my whole style and the gallery still didn't work. It displayed squares in a vertical line.
Since I have pretty high traffic (5-7k visitors a day) I could not leave it broken to show you nor temporarily revert back to the default theme.
