This awesome video shows us how to use Nav.Net Fusker Engine to find images from private photobucket accounts. Just amazing.

Nav.Net has lots of features other than Fuskering Photobucket. It can download videos from video sites, search for images or videos from sharing sites and spider TPG sites for hidden content. I recommend you to join Nav.Net forums. Nav.Net experts shares a lot of info about Nav.Net and fusker techniques there.
