Flickr has find an interesting strategy to capture the visitors that arrive to the website through Google Image Search. Each time you arrive at a photo page using Google, Flickr will provide a yellow note just below the search with the text:

We found 262,353 photos matching [keyword]. Click "search" above to see!

Also the search box is prefiled with the query.

All in one, a simple strategy that could boost the pageviews by a few percents.

Example:

Only seems to show when you're not logged in to Flickr. Find this a perfectly fair strategy though from Flickr. They might even consider breaking out of the frame when you click on that search, instead of staying in...

Thanks for correcting the post Philip, I was a little sleepy :)
Yes, that's correct appears only when you are not logged in. As about breaking the frame might result in a long term penalty so they'll stay on the safe side for a while

What makes you think Google would penalize someone breaking out of their search frame, after the user performs a second click? And even with a direkt breaking out of the frame, have you heard of such penalties?

As far as I remember no, but if they allow Flickr to do that, soon every site will be doing it and that won't be so productive for Google. Is just a guess
