It does, you don't have to run adblocker on the whole site. Simply find the image causing a problem, right clicjk, ad-block > block this ad.
Either way, this doesn't solve the problem. I certainly like looking at signatures, but when they are resized wallpapers or similar... No. Also, this might work for me (but it's way too much work to look for large pictures anyways), but we have people who may not install anything on their computers (how did they get sa:mp?), including browser addons.
