Turned out there was a problem with a page parser (or with this website, depending on your point of view). Full-size image addresses on twpornstars.com were shown like this:
https:///site.com/image.jpg
(3 "/" characters instead of 2).
The new version of Extreme Picture Finder handles these kinds of addresses correctly, so you will need to download and install the most recent version of the program first:
Download Extreme Picture Finder
Then download and install this template:
twpornstars.com downloader
It should work not only with the twpornstars.com website but also with all twxxxxxx.com websites listed at the top, like twonfans.com, twteens.com, and so on.
Please try it and let me know if it worked for you.
