This thread sounds like a lot of fun, so I'm game! I first posted pics of my wife back in 2007 on another site. Finding them on other sites is such a thrill for me.
My (or rather hers) greatest hit to date is actually of a short clip, just 10 seconds long. In it she playfully opens her towel and shows what's under. Somebody reposted it on dailymotion and I found it totally by chance. It had some 300000 views! It gathered more than half a million views before they purged it along with all the other good stuff. It ended up on various other sites as well, and even on this one
P.S. I'd also love to chat with other people hunting for where your pics are shown. What techniques are you guys and gals using?
