title: Transparency of images in Outlook 2007/2010 and LotusNotes
body: <p>I have the following problem - I cannot render transparent images in Outlook 2007/2010 or  LotusNotes using the '<code>opacity</code>' CSS element (using <code>style='opacity: 0.4; filter: alpha;'</code>)  because it is not supported. </p>
  
  <p>I didn't manage to find options in any of the clients that would allow for the rendering of the element either. Some options that come into my mind are:</p>
  
  <ol>
  <li>Use another styling technique;</li>
  <li>Render another transparent image from the original one and pass it to the content of the message;</li>
  <li>Leave transparency (this is the least desired option).</li>
  </ol>
  
  <p>Any suggestions would be of help. Thanks in advance.</p>
