title: ImageResizer not working with virtual directories
body: <p>I am using the ImageResizer successfully on other areas of my site where the images are being served from a folder within the application (both .jpg?width=100 &amp; .jpg.ashx?width=100 work),  but when I try images from a virtual directory located on the local machine, I can only get resizing to work if I specify the image page using the "jpg.ashx?width=100" method. </p>
  
  <p>The site's application pool is using NetworkService identity and the virtual folder has pass-through authentication enabled.  I've granted Modify permissions to NetworkService on the virtual folder too hoping that would help.</p>
  
  <p>I am using IIS 7.5 in Classic Mode and the resizer diagnostics page doesn't show any issues.</p>
  
  <p>Does anyone have ideas on why this may be happening? Any help would be appreciated.</p>
  
  <p>Thanks!</p>
