I’ve been testing this offline for a while now, it uses the yahoo image search to get the results.
at the moment its rather simple, I will add the ability to search for image types e.g. bmp, gif, jpeg, png and colour or b&w pics as well as results per page.
Currently it links to the site the image is on, however I can make it link to the actual full image and have a link to the site under the image.

its just a simple tool 
thought you guys might find it useful, since its not really related to hardware forums
