well if it's an animationt then it'll definatly give you that option for a gif, but for every thing else
just copy the pic, paste it in "mspaint"
and then save it as anything you want...or you can just switch to firefox [img]graemlins/hehe.gif[/img] which i did recently, tis fun to use and well stuff like that doesnt' happen as often
hope that helped
