Where can I find image search data? Ie. how many times is a query entered into images.google.com per month? Ideally it would be related to google images, but I'd be interested in seeing any data related to image search queries -whether it's from flickr, yahoo, aol or whatever.... Any advice?
You might not be able to find such information. Your next best bet is to use a regular keyword research tool and look for searches that include a word like picture, pictures, pics, pic, image, images, etc.
