currently there is no persistant image storage and images are generated on the fly.
for the purpose of prototyping this is fine and dandy but sanity requires some sort of persistant caching.

REQUIREMENTS:
- memoisation for the image generation
- some persistant dictionary to keep hash of arguments as key and image as value (maybe filename)
- ability to purge / force regenerate cache

this way, when reloading without force key, given same argument, image shouldn't be generated
