That looks like the regular Gallery homepage to me, only with some edits. Simply removed categories from the top, got rid of the ugly author infos and added some more rows to the latest images. So of course there is no infinite scroll. Made similiar edits a couple of times too, only a few lines in the template.
The plugin from this thread works fine after some cosmetics, but I don't share the link because it's an adults only site. Oh, and not my own too.
