can anyone assist with the header differences between a JPG and a Progressive 
JPG, I have a current project that extracts graphics resolutions from standard 
graphics formats but are having trouble getting it to recoganise a progressive
JPG. Which byte(s) in the header are read to distinguish between the formats. 
 
thanx in advance
