Is Google biased?

Google has been accused of bias from time to time against conservatives. (See here and here as well.)

I was looking for incidents in Iraq where terrorist actions led to the death or injury of children, for yesterday's post. I searched Google Images for "Iraq children casualties", and found something interesting.

There were 29 results. (None of them were photos I linked to yesterday.)

Of those, the sites that contained the various photos broke down this way:

Sites that said incident of injuries were the fault of the US: 8
Sites that were otherwise anti-US policy: 7
Other non-Iraq related sites: 7
Sites with general Iraq news: 6
Sites that said incident of injuries were the fault of the terrorists: 1

Yes, of those 29, only 1 photo was in a story talking about an incident where a suicide bomb or something caused injury to children. Compare that against 15 that were on sites actively opposed to US policy, or actually blaming the US, such as incidents where US bombs caused civilian injuries.

Is this indication of bias? I don't know how Google ended up finding these 29 images, but was interesting, nonetheless.
