Hi! Let me explain (because I can read everything that's written there)...
PhotoSight.ru is a huge resource. What you pointed out is yet another way to navigate the site. I would think that the photo you noticed was simply posted right before or after Ralf's photo. Hence on "The Big Filmstrip" they are together. If you open the link you posted and look at the same location (bottom left) - you'd see a clickable thumbnail of Ralf's photo. Hope that clarifies things a bit.
At the very bottom of the page which shows your picture (nice shot BTW), is a thumbnail link to this image: <http://www.photosight.ru/photo.php?photoid=1407795&ref=section&refid=999> Although IMO she doesn't look underage in the full size shot.
