Not just for images. Bing seems to be a lot more closer to what Google search used to be a few years ago. Anything related to torrents or streams is pretty much impossible to find on Google. Any news not spouted from mainstream sources, gone from Google. My default search deck nowadays is a mix of Bing and DuckDuckGo.
it's nice to see my vague worries, bothering me in the back of my head put into words. Also good to know that i'm not crazy for thinking googles results are surpisingly poor and generic. I sometimes get the same feeling using google that i get reading a poorly transalated manual from a Chinese company. Generic, admire the fact some effort has been made, little laugh inside. Except this is google (and ironically, the chinese copywriters are probably using Transalate)
Yandex is surprisingly good at image search and allows you to crop the source image in-browser.
Yandex is CRAZY good. There's a Firefox plugin that lets you reverse image search from the right click menu, and it opens a tab for Google, Bing, Yandex, Baidu and TinEye. Yandex is the king every time.
Bing had a problem with images of child sexual abuse, and with bestiality images. I don't know if they've fixed that.
