Dont save them as png, save as jpeg. it makes the filesize alot smaller. It took a while for them to appear fully. and i dont have slow internet
thats not the files fault. they just upload from a free server, since i dont have one of my own. The server sucks, therefore long upload time..
Well I htink the third is the best one. Also, most of us dont use our own servers to uplaod our sigs. We usually just use photobucket or imageshack.
