Really great addon for adding image search into Firefox (and forks of it). If I could suggest it, can you add Copyseeker(.net) to the list of supported engines? It's one of the best imo.

неплохо работает

very useful

lots of options is nice

GOOD experiance

Good add-ons for image search, but have some bugs, as searching by bing always jump to result of "cn.bing.com/images/search?q=World+tourist+attraction&form=HDRSC2&first=1", i don't whether it work well outside china
