Making album art into windows folder picture

Hi all,

In Windows Media Player (11), when I paste a picture as album art, then when I look at the folders for my music in thumbnils view of windows, the folder has the picture of my album art the full size of the folder. When I export my album art with mp3tag, I only see it as a 1/4 size of the folder, until I manually chose the folder picture in the Customize tab of the folder properties. Is there a way to automate this?

Thanks again for such a great program!
