Show dynamically generated CAPTCHA image on IIS8.5

Question

Hello,

I have some pages on my web application that require the use of CAPTCHA images. In order to dynamically generate these images, I have a <asp:Image> which has the ImageUrl referencing the CImage.aspx page.

The CImage.aspx page randomly generates the CAPTCHA .jpg upon page load. The problem is that this doesn't not work on my IIS8.5 server. It works just fine on my local machine when testing with Visual Studio.

From what I can find with simple google searches, I believe this has to do with the Handler Mappings in IIS... However, I could not quite figure out what I needed to do to get it to work...

The code I'm using for the CAPTCHA comes from: Captcha Image using C# in ASP.NET[^]

If your main problem is just translation, you can easily do it automatically: Code Interpretation, C# to VB.NET[^].

I would like to emphasize the easy and good quality of the off-line translation with open-source ILSpy, but to use it, you will need to put all the code you need to use in some project, build an assembly and then disassemble it with ILSpy. The quality and reliability well worth the effort.
