People who are new in the field of Image Processing and want to work with jpeg files can get the jpeg libraries and instructions to use them from following link
http://www.ece.sunysb.edu/~cvl/e358/f2001/jpeg-windows.html

Also there is a project at this link
http://www.ee.sunysb.edu/~cvl/ese558/s2005/ese558_2005.html which
describes how to use these libraries to get a jpeg image into a 2d array and
do whatever with it afterwards.
