That's not necessarily a Google problem; image ads do extremely well for me. I've tested and tested, because it goes against what everyone always says here, but nevertheless, my image ads kill. The CTR is slightly lower than text but the EPC is really really high.

I don't see how any of that has anything to do with DFP anyway, it's mainly a delivery system. I don't use it because I don't have time to deal with their ridiculous learning curve on it. But as far as I know, DFP only serves what YOU tell it to serve.
