Google has basically given up on their image search product. For that matter, their main search product is getting product long in the tooth. It's in the position Microsoft was in during the old days of IE6. Yandex is a good option. Bing is another. I usually prefix my google searches with a domain these days. Instead of merely subtracting a domain, I fix it to a domain I know is good.

Google's IE6 search product needs its corresponding Firefox to give it a kick in the shorts.
