The AdWords Operations team is asking for your photos. They are going to decorate their building with it. Why?
Actually, they are moving into a new building and they "want to decorate our new building with photos of our advertisers as a way of recognizing that we owe our success to you." In a post at the Inside AdWords blog, the team has said that:
We'll be showing the photos in the new building because seeing your faces inspires us and reminds us that we're here to help make our advertisers more successful.
You can the details of how to send the photos here. Along with your photo, the team also request you to "include your name, your customer ID number (so we can match you up with your account), your business name, and a description of the photo. High resolution images, greater than 5 megapixels, are best. We'd also love it if you could include a paragraph describing your business and how you are using AdWords."
In return for the gift you will receive a small thank you gift from Google.
