You don't. Unfortunately, Photobucket changed their business model a while back such that you can't "hot-link" images to other sites unless you pay them a lot of money (don't know what the current rate is) to become a "Pro member." Unfortunately, before they made the change, many members here were linking to images on PB in their posts here. But then, when PB made the change, none of those images could be viewed any longer. It is PB doing this and nothing we can do about it unfortunately.
