Body: <p>I received a 250MB epub file
  and unzipped it (with 7z) and just recompress it's jpeg's to ~50% size (not dimensions), keeping the same files names (with IfranView).</p>
  
  <p>I reziped to .epub and loaded it to my android tabs.
  Two apps open it but will display each picture twice. 
  Once without adjacent text and the second time with text 
  <strong>I do not have any special epub authoring software</strong>.</p>
  
  <p>Why it happened and can I correct it?</p>

  After so long I came back to this issue and found the solution.
  
  1. I open the epub in 7z (but not unzip)
  2. I drag the image folder out and recompress it with Ifranview to my liking.
  3. Now I drag it back into the open 7z window to replace the old image folder
     close 7z, and now the epub is half size and opens correctly in any epub app,
