Don't think this is directly ZP problem, just not sure what the cause is.

From the Admin pages, I select to view my Gallery and select an album. I'm finding the thumbnails don't fully load. Many only show their alt-tag entry. Even when I've cleared the cache on browser and in ZP. Do I cache the images? Not seen this problem before, as bad. Occasionally if working on the album thumbs page for a long time it'll happen. Now it's all the time.
