I'll give you a small hint. This plugin will copy all images from FHG's, will crop the thumbs and insert them right into your WordPress posts:
Gallery Magic – CyberSEO
It also will put your own link, banner or whatever HTML code, so you won't care if someone will redirect the original FHG's, because you'll gain a 100% control on the picture content. You can grab the FHG's manually or import them from a text dump.
