    I'm sure if you hit up your favorite search engine you could probably find some sort of library to do some of the work for you. But wotsit has file formats if you want to roll your own.

    Hope is the first step on the road to disappointment.

    what does this mean? you want to read the codec bytestream in a JPG file? so that you can ... manipulate and modify the image? you need to first understand the JPG file format. and you're probably in for a long afternoon.


    or... do you want to read the meta-data tags in a JPG file to get info like camera model and settings, image size, date picture taken, etc. etc. ? I suspect this is what you want. Here is the EXIF specification, and here is the libexif C EXIF library.

    have fun!
