title: Dynamic transparent images using AlphaImageLoader in IE6
body: <p>The following code works fine when I have an image in IE6 that i want to make transparent. </p>
  
  <p><code>&lt;img src="image.png" style="width: 100px; height: 100px; filter:
  progid:DXImageTransform.Microsoft.AlphaImageLoader(src='image.png', sizingMethod='scale')" /&gt;</code></p>
  
  <p>However the following does not. In this example I am using a dynamically generated PNG file.</p>
  
  <p>I assume its because the filter doesn't know that the image is actually a PNG</p>
  
  <p><code>&lt;img src="/dynimg/createImg.aspx?id=123" style="width: 100px; height: 100px; filter:
  progid:DXImageTransform.Microsoft.AlphaImageLoader(src='dynimg/createImg.aspx?id=123', sizingMethod='scale')" /&gt;</code></p>
  
  <p>Is there any other way to apply the 'filter' and force it to assume that my image is actaully a PNG.</p>
  
  <p>Note: The image.png file in the non-dynamic situation was actually generated by my dynamic aspx page - so theres nothing wrong with the dynamically image created.</p>
