Dynamic image generation / hosting.

I give you a baseline image. You dynamically modify that image and host it for me based upon (ideally encrypted) parameters that I pass you.

Example use case: I send an email that features a thermometer that shows how far from $100 your balance is. It dynamically calls this service to generate a thermometer showing your $96 as meaningfully different from my $22.
