     USAGE:
          This package has 3 function to manipulta jpeg images with php code.
          - resizeImage : needs a filename and a width, height values.
          - dropShadow  : needs an image as image resource and not as filename, and you can define 
                          the shadow size.
          - createBorder: needs an image as image resource and not as filename, and the border 
                          width and height values.
