            {

 //keep wiritng the current image
                fwrite(buffer , sizeof(buffer) , 512 , img);



            }









        }

        fclose(img);
        fclose(file);






   }






}

It's always the little things. ;-)

Simple problem. The filename extension is supposed to be "jpg", not "jpeg". Lose the "e" in the filename creation statement.
