compared to what? to text ads or to blank space?
Compared to text ads, of course.
My primary sites have virtually no images (other than the image ads) That might make a difference, I dunno. Also, my sites are locally focused, and the image ads *I* usually see are for local businesses or organizations. I'm sure that helps as well.
