title: Decompress "wmz" file
body: <p>When we try to save msword doc file as html file we get "wmz" files for the math equation objects.</p>
  
  <p>I tried decompressing the wmz file and saving the content as jpg.</p>
  
  <p>I can open this jpg file in the "Microsoft Picture manager" properly. But trying to open the file in browser displays the error message "The image cannot be displayed, because it contain errors".</p>
  
  <p>What is the procedure to decompress this wmz file and convert it to jpg.
  What will be the extension of decompressed file?</p>
