That is what I have done, and the result is as you see it. The strange thing is, it worked when I first did it, and then when I went back the following day it was no longer loading the images. Yet the work and load okay on the forum pages...
I will have a check of all the other settings, just in case I change something else by mistake... (happens a lot to me...

hence the test forum... )
Will let you know if I find anything...
