compacting images

[Dave Dyer]

I create all my graphics on the fly, so the internal representation is whatever createImage results in.

Would there be any storage or performance changes (for better or worse) if these images were converted to statically
created images, loaded normally?   Is there a way to make this transformation other than actually
writing them out and reloading them?

There is a lengthy discussion of the various image types, their tradeoffs and how to get them in the graphics section in the developer guide.
