I think many of us have voiced this concept over the last few years. I love the idea of Google serving as the main search engine if they could somehow bundle an e-commerce function and an image delivery system with it. Sort of an ebay style delivery system where we control what, when, and how the images are delivered after we're paid via Paypal or similar. I would think they could take, say, 10% = 20% off the top and do well.
