...being that Photobucket has now changed their user policy to a pay subscription, a lot of  3rd party linked photos have now disappeared from the forum. But there is a patch that has surfaced in recent months for google chrome & firefox browsers to make the pics viewable again.

FireFox

There's other free image hosting sites available yet like 
Flicker
Image Shack
Imgur
