Detailed file format information is available at:
http://www.wotsit.org/

Beware, this is not an easy task, particularly for JPEG. The
algorithms are fairly complex. If you are allowed to, I suggest
looking for existing portable libraries.

This really isn't a C question. You might have better luck finding an
answer to your question by selecting a newsgroup in the comp.graphics.*
hierarchy and asking there. Also, consider a web search. For example, I
plugged '"PNG specification" format' into google. This was the first hit:

You're welcome, I hope you find what you are seeking.
