I did a presentation on writing plug-ins in GUADEC - *very* basic but there is a sample plug-in included. The paper is online at http://dneary.free.fr/gimp > I guess I have to write a plugin but the docs a rather outdated (at > least the ones I can find).

The one I usually reccommend is pnm - in the GIMP sources, this is in plug-ins/common/pnm.c. This is good because it shows the basics of saving and writing an image without having the overhead of using a 3rd party library, or having file format overhead involved.
