Pick an API that can just draw a single image rotated in whatever way it wants. Most hardware accelerated 2D or 3D APIs can do this.
If your API of choice can't do that, then for games you really only need to do one image per every 15 degrees or rotation, or perhaps even less (every 22.5 degrees or something).
Every 1 degree = 360 images for every one image you want to rotate.
15 degrees = 24 images for every one image you want to rotate.
22.5 degrees = 16 images
45 degrees = 8 images
