The problem with htpd/image is that the pinholes are constantly in your
face.  (Also, they're part of the images identity, even though they're
not visible.  Huge pain for writing test cases.)  Maybe an alternative
API could alleviate that problem, but I'll believe it when I see it.
The deinprogramm/image teachpack is essentially htdp/image without the
pinholes, and we've been running with it since 2006 - and have been very
pleased with the experience.
