(resolved)Xthreads Thumbnails Not working anymore

[ZiNgA BuRgA]

So is this behaviour _always_ alternating exactly like this?  That is, fine, broken, fine, broken pattern, or is it sometimes fine, fine, broken, fine, broken, broken, fine etc?

Try copying the image location of a thumbnail when it's fine, when it's broken, and when it's fine again.  Are the URLs always the same?  If so, visit the URL of the image thumbnail directly, and try Ctrl+F5 a few times and see what happens.

Also, do you have any form of hotlink protection enabled on the server?
