Well, I made *some* progress...I put a slash (/) in front of "include" and that didn't work so I removed it and re-uploaded without the slash and for some reason that got the scroller working, but the thumbs don't show up...

UPDATE: Well, I'm completely stumped on this one. On one site where it's in a subdirectory, the roller works except the thumbs don't show up and the same exact file in another site in a subdirectory doesn't work at all, when at the least, it should be behaving in the same exact manner.
