HI Gaz:

Please don't use the albumcover.py anymore, it's old and has bugs. Please install Canola-Tuning to make this works. This -o for the output does't matter that much, because canola will always look in the ./canola/covers that's why you need the link.
then when canola looks for cover the system redirects to the file you created the link.

We teste here.. it works the way I sent you.. if you can test that... you don't need to touch anything in python =)
