Better then nothing? Actually, I'd stick with the generic cover instead.
An image that small and that aspect ratio incorrect will look awful. Sometimes it takes a while to find the best possible cover I can using Google images and even then I sometimes have to make do instead of getting a cover image I like.
This plugin is a really bad idea unless you can give it a URL and it will go fetch the image and put it in as the cover. Then I'd agree it can be useful. But otherwise, bah!
