title: Decompressing a compressed image using PIL
body: <p>I have compressed an image in python2.7 using PIL library like this:</p>
  
  <p>picture.save("Compressed_"+file,"JPEG",quality=85) </p>
  
  <p>Can I decompress it? 
  I have searched so many sites, but couldn't find decompression related information.</p>
