Have a look at the spec-XXX.tex files, these define the driver macros. Look for things like \definefileinsertion. Adding PNG may not work straight away. Two main problems to solve: - The size of the image has to be available to the macros. I am not sure whether pdftex accepts png images in DVI mode. Anyway, finding out the size is doable (using an external program if need be). - The other problem is the precise syntax that the DVI driver needs. Just saying 'it supports' doesn't help. TeX \specials are basically strings, and you need to know what precisely the viewer expects to find in this string. If both of these have been done, the macro for inclusion itself is fairly trivial. -- groeten, Taco
