Image ads do quite well for me in some spots.

compared to what? to text ads or to blank space?

hypothetical adsense earnings example for one banner per month:

text only: 100$
text/image: 105$
image only: 5$

which option optimizes revenue? obviously text/image.
but am i willing to give image advertisers a free ride for 5 bucks a month? nope. i choose text only.
