i am using the racket build with 2htdp/image
and 2htdp/universe and capping the memory at 512 MB. Is there anyway, I can
preload the images for universe and then use them (almost like the java
way). Or is there some place i can store the images in some sort of hash

Basically, instead of loading images at the second you use them, can you
load it at the beginning of running a program.
