What kinds of images should we highlight in the slideshow on the main homepage?

The new website provides an image "slideshow" or "carousel" to highlight various things.  Currently we have an image of Shannon, ISIT 2008, and the Transactions (which is a bit too low-res for final production).  Some graphics work is required for someone to submit an image with the right dimensions, but otherwise posting the image is pretty trivial.

Ideas:

• Shannon
• Upcoming ISIT, ITWs
• Transactions
• Most recent Shannon Awardee
• School of Information Theory
