Hi Sean 
   
  what u say is absolutely true, and that is why i had decided on JPEG scanned pics.
   
  my problem is getting hold of a jpeg decompresion s/w (by the way ..i write in C using Keil) ... maybe u could point me to a suitable source ??
   
  thanks for renewing my interest in jpeg !!!

  Except using 8-bit BMP files is not only less colour resolution, but 
a lot more space than a JPEG file.  Considering that there are 
plenty of jpeg decompression routines available for use, why not 
stick with jpeg?  Flash space is pretty expensive on an embedded 
device (unless you're using SD card or something), but still...
