Error: Capture Screenshot not working after Publish in IIS

Hi, first of all thank you for what you do.  This is a great source of information.

I have a question about your ASP.NET Capture Screenshot code.  It works on my local PC, but when i deploy it to an IIS server and browse to it, it does not work.  When i click Capture, the page just spins forever.  Please let me know what i might be doing wrong.

Thank you,
