Folks:
I think I've checked everywhere, and have not seen any mention of this problem.

I just upgraded from .18 to .20a, with the .20a plugins. Mythgallery builds just fine, and displays thumbnails as it always has. However, when I try to display any single image at full size, it shows a black screen.

If I run a slide show, I can tell by looking at my LCD display that the images are changing as they should, but of course all are blank.

Anyone have a suggestion of where to start?

Best,
Tb.

Do you have proper permissions to the /myth/gallery/X directories and the files within? The thumbnails are typically stored in /myth/gallery/.thumbcache, I wonder if the permissions on the other directories/files were adjusted during the upgrade(s)...

Turning off OpenGL transitions in the setup wizard seems to have solved the problem. I don't yet know why, as they worked fine with the .19 version. I'll chip away at it.
