right now i am using bing's images , very good and new images , google have good images but upto 3-4 pages. so i will give you advice to use bing once and see what happens.
I think he is right , many times after 4 to 5 page google start displaying images different to our requirements .
Thanks for sharing this resource. Currently i am using bing's too in looking for images and the result is pretty good.
