ok, I created to my main domain say
www.myforum.com a subdomain
avatar.myforum.com and after testing, still the avatars are not showing!!!
I'm sure there is either a glitch in the vb board or something else need to be configured!!
any idea?

ok, I got it solved myself. I had to have the same root path as my main domain on the new subdomain, and now things work fine.
