Right click "Save picture as" then once you save it upload it to Photobucket. Then when it is up on P.Bucket you will have 3 link choices displayed. Right click on the top one... the URL link click copy.
Then open your About Me thing on Scrap Yard forum, scroll down to your avatar click the box to Add URL avatar. Right click in that box choose Paste. Then scroll down to the bottom of the page and click submit.
Done. Oh if you don't have a Photobucket account it takes less than 60 seconds to set one up. And it's free.
Peace.
