asp.net image display as a percentage
<p>I have a page that accepts image uploads up to 4MB.  The images can be as small as 100x100 or even as large as 1900 x 1200.  I'm using a pop-up window to display the uploaded image.</p>

<p>The problem is that I want to scale the larger images programmatically (but not modify the image itself).  I want to display the large images at 80% (or 60% or whatever) if possible.  I've seen browsers display an image at XX % then when you click on an icon, then the image will be displayed at 100%.</p>

<p>That's the effect I'm trying to accomplish.</p>
