A DigitalPoint Forums thread links to a contest that Google's AdWords department seems to be running. The contest asks you to submit your photo with a chance to have them displayed at Google AdWords.
We're redecorating here at Google AdWords and have decided on a theme: you! We're looking for photos that feature our advertisers and the unique nature of their businesses. If you're interested in having your photos displayed here at AdWords, send them along to [email protected].
Photos need to be submitted by February 28, 2007.
There are more details with photo ideas and the guidelines at http://www.google.com/adwords/photo_submit.html.
Update: Official Google AdWords Blog post on this at this URL.
