We offer most of the standard ad units and some additional.
All have a maximum size of 40-60k. We have:

* TreeHugger's ad units accept both standard image file formats and rich media creatives, including Flash 8. We work with all third party ad technologies, including Motif, Eyeblaster, PointRoll, and Klipmart with up to a 100k polite download.
* Expanding ads require user-initiation with a mouseover or click and audio ads require user-initiation with a click. Both need a prominent close/stop button.
* 5x looping restriction for all sizes except 300x250
* 90 second limit on animation for all sizes except 300x250
* We serve banners via iframes on all sites, so please note that rich media may need a local html file implementation for expanding creative.
