title: Customizing the dialog image and banner image in WIX installer
body: <p>I had Created <strong>wix installer</strong> project to my C# windows forms application.</p>
  
  <p>I am  new in using wix Toolset. I am wondering if there is anything like theme file, from which I can change the dialog image and banner image, as I need to distribute this installer for different customers, and I should set the look and feel of their logo. I want them to feel like this installer is customized specially for them.</p>
  
  <p>I mean, I don't want to change the dialog image and the banner image each time from inside .wxs file. I imagine that there may be something like a <strong>.theme</strong> file from which I can set the images every time I need to change it.</p>
