I am having the same issue. We moved a site from a development domain to the real one and now the pictures are missing from the gallery. When I inspect the elements of the pictures that are missing, I see there are referencing the OLD URL.
I figured I could do a search and replace on the DB like I always do, but for some reason I cannot find the OLD URL in the database. Are these stored somewhere outside of MySQL?
Please help! Thanks!
Eric
