By choosing to display image ads in addition to text ads, you can help ensure that you'll have all available advertisers bidding to appear on your site. Both text and image ads will compete in the same auction to display on your pages, and we'll automatically display the ad(s) that will be most effective for you on your site.

If you mean that they pay the most per click, then no, in most cases I don't want those.
I want the ads that get clicked so my check is the biggest at the end of the month.
$2 X 0 clicks = $0.00
$.03 X 10,000 clicks = $300
To me, it isn't worth worrying about how much the ads pay. Sometimes I get $2 clicks Sometimes I get 1 cent clicks. What I want is on topic ads that get clicked. In the mean time I prefer to worry about increasing traffic and content.
As for whether to select image ads or text only, follow Google's selection elsewhere and do A/B testing. I usually have images turned on, but with the obnoxious HR Block ads taking over all my sites, I'm turning image ads off or rotating them in only a small percentage of the time.
The very first site that I turned images completely off on was my 1 month old site that is getting 20-40 uniques a day. It is my larger sites where I am keeping them on for 10% of the views, not my smaller ones where I am trying to build traffic.
When they run on-topic image ads, I was fairly happy about leaving it on. But I actually care about the ads my visitors see. I don't want off-topic ads or annoying animations, even if they pay better.
<added>And high CPC ads don't pay better on a low volume page than they do on a high volume page if they don't get clicked. Worry about what you take home, not what a particular ad pays. The ad that pays $20 for real estate in Malibu isn't going to do you any good for your site about restaurants in Liverpool, even if it is high paying</added>

image ads have lower CTR
they don't have higher EPC than text
They tend to take over too many pages with same ad.
Aside: My ctr used to be much higher when G always showed 4 ads in the large rectangle. Now I rarely see 4 ads -often two and sometimes one. If i wanted to display a single ad I would have chosen the 125x125. Therefore I vote for as much variety as possible with out having multiple or huge ads.
