Google keeps talking about the real-time web and that how quickly it can respond to real-time events. However, Google image search doesn’t work that way.
Peter Linsley of Google Images shares some simple yet important image optimization tips that might help you get more traffic from image search engines:
Users prefer large, high-quality images (high-resolution, in-focus).
When I searched for images of domino’s pizza on Yahoo Images, the suggestions included McDonald’s, Pizza Hut, Burger King, KFC and Subway – all fast food chains.
Google Image Search displays thumbnails as results, with the original image another 2 clicks away. “Google Image Ripper” lets you get “straight to the good stuff” by linking directly to the original images.
Yahoo has added some very useful filters in their Image Search engine. For instance, you can specify dimensions (height x width) in the search query and it will display only pictures / icons that exactly match the size.
Google Image Search offers some unique features that aren’t available in the default search engines of other photo sharing sites like Flickr, Zooomr, Photobucket, Facebook, etc.
