Not just images. I've noticed that Bing also gives results which helps me fine tune the search terms better to get more accurate results.
Most of the time Google gives me a correct result ONLY if I know exactly what I'm searching for. But that's usually not the case.
Even for technical searches, I notice that many times, Bing gives a more varied search result which helps me.
Conversely, on Google after the first few links, the rest seem to skip some words from my search entirely. It feels as if Google is just trying to give me links to fill up the page and then I have to go back and put double-quotes against each term. Even after all that, I only get what I want more and more rarely.
Of late, I notice myself relying on Bing more frequently.
