I am continuing to work on my TGP which you'll find at
ApexPornPics.com. Unfortunately, I find the script half baked. From my experience, you can either run it as a fake TGP without webmaster submissions or a community / user based site (like imagefap.com) where people upload their pics. What it really needs is the ability for webmasters to upload their pics, add a sponsor banner and a back link to their site. My understanding is, while they'll write this functionality in for a fee, the program is not likely to be upgraded from what it is now.
To that end, I've been researching what might be available for a link directory in WP. I found this plugin which looks interesting but also has some limitations too --
Simple Link Directory. I might do something with it sometime with an other domain.
I am hoping as I feel better, I can really go to town on this in June.
