Well, its all in the title, I seen a mod for vbulletin that does this so want to know what the html / css equivalent is I want to have a .PNG logo on my site, but not have it so that ie6 users see the blue background. I know they can patch their IE but is there something i can do so they dont have too? P.S i know less and less people are using it thanks to ie7 but i still want my back covered
