@Cameltopro: I know several people submitting to TGPs like clockwork, every day. Popular ones like Elephant List, The Hun, Thumbnail Series, PinkWorld, Library of Thumbs, Shemp's Outlaw TGP, Greenguy's PornLuv, BabePedia, FreeOnes, and many others.
Konrad: Your script was/is awesome -- I own a license as well. But it is not a TGP script, at least in the traditional sense. Rather, what you built was a picture gallery CMS script. It can do plugs, and users can upload content. But it lacked the fundamental purpose of a TGP described below. I think this is probably a big reason reason why sales were slower than you likely expected. Webmasters who initially expressed support for a TGP script were likely searching for a TGPX replacement. And when your script wasn't a TGP/TGPX replacement, they re-visited TGPX. Indeed, it would be a niche demographic for a TGP traditional script.
That said, you could probably re-brand it as a Picture Gallery CMS and attract new buyers. It is indeed a good gallery CMS.
Regarding TGP sites in general. Most seem to be using TGPX, which was converted for use with php 7.x by Hincapie (a member here).

all use TGPX.
TGPX remains the defacto standard script because it offers the fundamental purpose of a traditional TGP script:
- Webmaster (Submitter) submits a gallery link to the TGP;
- The TGP posts the link to the submitted gallery;
- Submitter gets traffic back to their gallery/website from the TGP (to promote their sponsor)
They're not as popular, but there is absolutely a demographic that enjoys picture galleries.
