They are graphical ads. Image ads are also targeted to the right audience, just like text ads. A writer that has both image ads and text ads has a greater revenue generating potential.
Image ads are only for Adsense for Content pages and not available for Adsense for Search results pages.
There are 5 kinds of image ads. The Leaderboard, which is about two times the size of a banner ad, the banner image ad, the skyscraper, the wide skyscraper and the medium rectangle. Google's determines on every page whether image ads, text ads, or a combination of both will make you more money and then delivers the correct format.
You can choose to run only image ads, but Google recommends selecting both of them, thereby giving them a better chance to target the right advertising for your page, generating more money for you.
Bottom line: taking these two methods together will give you the best chance at making the most revenue.
