Yea..DOwnload Lightshot or Gyazo..or Anything..nd then take screenie..
Would it work with just the url? Or does it have to be downloaded
You could just take a print screen of what you see for you signature rank. Then cut everything out in paint, so it's only what you want in your signature and save it. Upload to tinypic and use the img url like so:
[img] Image url here [ /img] (Just backspace the space between the bracket and /)
This way you don't have to download anything
