  <p>As per above HTML actual image url is prepended with a Google proxy URL stopping images to be displayed. If we remove this garbage URL, image starts to appear fine. Same issue not appears for Apple Mac Mails.</p>
  
  <p>We have provided mailing feature using Java Mailing API. Please suggest.</p>
  
  <p>Thanks,
