Dear Lynne
thanks for your reply , but I think the header of vBulletin set it to "no-cache"
Code:
<meta http-equiv="Pragma" content="no-cache" />
so I think every time user load that page , it should load everything again , not from the cache , am I correct ?
By the way , I remember vBulletin has a function , user can turn that function off
then the picture we use will become a link , not a picture .

but if they turn it on , it will show picture directly .
