c#

I want to put an unique image (1x1) on an e-mail marketing (not spam) of my client. Just like www.spypig.com, I'd like to use it to know how many people have actually read the e-mail. I guess I'll have to check how many times this unique image has been accessed, but I can't figure out how to do it.

So my question is: Is there a way to check how many times an image file was accessed using ASP.NET/C#?

Thank you
