Image sprite

Hi - I'd just store all the images (as you'd get from the image generator site) into one big file one after the other and store the offsets somewhere.

Then:

var images = require("Storage").read("myimages");
// note 'images' is not actually using up your RAM, it's still stored in flash

g.drawImage(images.substr(offset,len));

The substr will do a copy of the small image into RAM, but honestly if it's a small icon that's not going to cause a big problem.
