I am trying to use Google Search by Image, which was apparently implemented in July. Here are the instructions
You are supposed to be able to drag an image from your computer onto the search box at images.google.com to search by image. When I drag and drop, the browser just loads the image (such as file:///C:/Documents%20and%20Settings/Home/Desktop/some_pic.jpg).
Also, there's a camera button on the end of the search box, and you are supposed to be able to press it to select a local file. When I put my mouse on it, it changes to a hand, but clicking it does nothing. I tried turning off my Firewall, and running Firefox in Safemode, in case an add-on was interfering. JavaScript is enabled.
Firefox 5.01; Windows XP SP3
