Some help is provided for the algorithm authors on a dedicated page, "Development Resources".
This includes some reusable simplified code to read and write common image formats, a task that seems to be the first obstacle when a portable implementation has to be written.
Some other formats should follow, and eventually the full source code of the IPOL online demonstration system, allowing IPOL authors to create their own demo pages.
update 2010-08-06: a portable high-quality pseudo-random number generator is proposed
