title: Is it possible to use .png images for WiX bitmaps
body: <p>I am using 2 500K bitmaps in to display images on my WiX dialogs.</p>
  
  <p>They dramatically increase the size of the installation package, and what is worse - it looks there's no way to package them as a part of a .cab file since they're <code>&lt;binary&gt;</code>-es in the WiX terms.</p>
  
  <p>So, I thught, is there any way to use other file formats for bitmaps or WiX is tethered with BMP? Ideally it would be greate if there's a way to use .png format since it comes with a looseless compression option.</p>
