Here's a new version I've been working on. For this you'll require .NET framework 2.0 installed.
Please report any bugs/glitches.

If you create anything useful with the source, it would be a good idea to upload it here for everyone to benefit. Note that I probably won't be updating this project again, except maybe to add scripts.
The license requires that you include full sourcecode with any modified version distributed.
It's messy code, and the first and only time I've used C#, so I hope it's of use to someone.
Included site scripts:
- Walmart.com
- Buy.com
- Amazon.com
RateYourMusic.com- iTunes Music Store

---------Old Version-----------
This version uses Python scripts to specify sources for cover art. Look in the CoverSources\Scripts folder for more details. Walmart.py is a good template if you wish to write your own (Amazon.py is a mess)
The commandline syntax is quite simple, just coverart.exe <Artist> <Album> <File to save to>
The second two parameters are optional, if a path is not specified it will prompt you with a Save As dialog.
You shouldn't require any VC8 runtimes; it's linked statically.
Extract the entire archive into one folder, there is no need to unzip or do anything with Python24.zip, this is the library for the built-in interpreter and can be read from the zip file.
Note: The scripts in this download file are NOT up to date. Use the scripts attached to this post. Put them in coversources\scripts

Updated Scripts for Rate Your Music and Amazon are attached (these are recommended over the ones included in the download archive, for example the Amazon script no longer returns results that don't have valid thumbnails)
Commandline for foo_run:
CODE
"C:\Program Files\foobar2000\coverart\coverart.exe" "%artist%" "%album%" "$replace(%_path%,%_filename_ext%,)folder.jpg"
