This is getting popular on twitter:
Go to Google images, type 'david cameron side profile' & check the 1st result.
(ps: sorry if I'm violating forum rules by posting NSFW content. feel free to delete, if so.)
haha! I didn't expected that :)
The "prostate exam" image is now the second result for me. The first image result is not even of David Cameron.
But, the top result is the largest image on a forum discussion whose topic is "David Cameron Side Profile", which makes me think that Google must assign extra significance to the largest photo on a page, even if it's well down the page.
I did a Google image search for "David Cameron side profile" and laughed.
