It's been a while since I checked yahoo and bing last time, my main traffic comes from g. It seems like yahoo doesn't even bother to show the original page in an iframe. So i guess there is nothing to breaking out from... They even created a nice gallery style browsing with right and left arrows, just pick whichever picture you like... People spent time and resources to create those pics and pay for the hosting so that yahoo can just give it to the users for free.
It's like having the whole page without ads shown in the search results, why would anyone bother to visit your website if it's already there?
I guess I have to put a huge watermark for requests from yahoo saying click here to go to the website!
