AlumniHi Andrew,
Measuring image similarity is a non-trivial image processing task, which is beyond the scope of general-purpose automated testing tools. You might want to use a specialized third-party tool or library for this purpose, such as AForge.NET or [url= http://www.imagemagick.org/script/compare.php]ImageMagick[/url], and integrate it into your testing process.
For general ideas on how to measure image similarity, check out the following posts on Stack Overflow:

I hope this helps!
