Can't download all pictures from page starting from main pag

[campilobaxter]

I'm trying to download a ton of pictures from a pay site. I can get pictures from a single directory just fine, but I want to be able to start PL on the main page and have it follow all the links and download all of the pictures through as many levels as needs be. When I start PL on the main page, it just doesn't find any pictures. Can anyone help? The URL for the main page with all the links is http://members.amateursgonebad.com/members_gmgb.shtml. I understand that I need to put the login info in the task options, and I've done that.

Thanks!
