Problem with attachment browser is if you have 10's of thousands of images the visual page by page search is needle in a haystack. Need something direct. How to decipher the image name and what post points to it. maybe a query or something
Awesome. You helped me track it down. Looks like this post was moderated so guest could not see but we could as admin. Found the image and some others on google webmasters as errored images and could see that guests were unable to view them. Wasn't sure if it was a permission issue or something like this so thanks to your advice we verified this so everything is working logically!
