jpeghead.h

/* This file was added by Nathan Stenzel <nathanstenzel@users.sourceforge.net>
   It will only get rough rough images, but might do for now
   I may be working on the header by decoding the image into a stream "manually"
   This is the Polaroid Fun! 320's header
   It should be modified for the Polaroid 640SE
   For the bennifit of anyone else that wants to try to figure improve this....
     ...I split the jpegheder into the different sections.
  I believe I did this right. I split it at FF markers that were not ended by OO
  Please email me if you can help me out.
  I need to figure out how to decode the image data by "hand"
     and then edit this header to fit
