If you want to store extra info like that, the PNG format also allows you to define arbitrary extra 'chunks' which other programs will ignore. Since that's much more widely supported, it might also be a good choice.
I was part of the original PNG team and reserved the fRAc chunk for exactly that purpose - but never did anything about it because the memory demands of the PNG library exceeded what we could manage with Fractint. I actually went to a lot of trouble to make sure that Zlib and the PNG libraries could compile with the medium memory model, but to no avail. WIth the DOS limitation gone, now we could resume looking at the fRAc chunk for fractal data. Tim
