I just use a raw binary dump and wrote a small program to convert from 
PNG (because libpng had good docs :) to it.

This image is displayed for ~2 seconds when the device (pulsed 
transmitter) starts up.

I've attached the program.

If I had to generate a font table I would probably just make an image 
which contained each glyph in whatever order was most convenient and 
store that in flash.

Unless you're storing on some sort of "shared" medium (ie CF, SD card 
etc) then I don't really see the point of an image parser, you may as 
well do all the work on the PC and make the micro('s programmers) job 
easier :)
