Google slips ads into its image search results

Google is going to extra lengths to make sure that you see its shopping links. The internet firm is introducing Shopping ads to image search results -- look for pictures of a nice couch and you may see a link to buy it. Google says this is largely about enabling more on-the-spot purchases, but there's no denying that this is partly about snubbing Amazon. After all, your first instinct may be to search Amazon when you spot that must-have item; you won't have to do that after today.
