WP plugin: Adsense Beautifier Increase your AdSense CTR with small pictures next to your AdSense ads. This plugin makes the process simpler. On a side note, AdSense has already started doing this on some of their ads. I have noticed it on my eBayToSMS page.
The question — as always with all things AdSense — is, does it play nice with Google’s TOS? The plugin’s post indicates that it’s not a violation; I’d like to get a ruling from Mountain View, officially.
