i am using the 5.0.1.1 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 map.
Basically, instead of loading images at the second you use them, can you load it at the beginning of running a program.
