Yes, that link points to another forum, and it IS the original source of the pictures. They are pictures of the wife of the OP of that thread, Luiss. He never gave her name but all the pictures ever released of this woman came from that thread on that forum and have been gradually released over time there. He started the thread in May 2009 and posted the last picture and made his last appearance there on Jan 9, 2011, page 49. There have not been any others released since then. There are 59 pictures on those 49 pages, the one below is from page 24. That thread is definitely worth going through.
I don't quite remember but I may have seen that other thread on this forum and may have posted a link to this page there too, or someone else did.
So even though I don't know about any other threads here, I just thought you might like to know the source.
Cheers
