2htdp/image is mostly for teaching purposes. I'd use the underlying graphics toolkit to create snips for that. I started an htdp/matrix snip library years ago (again for teaching purposes). It's a bit confusing at first but doable.

We welcome any and all contributions. 

Neil T maintains the math library and I am sure he will pipe in soon.
