What is the pixel size of the cover image?

I don't like Mp3tag's image reduction process, as it's fixed at 70%, which is too much compression. Using 90% is a better alternative. I wish Mp3tag offered different image compression choices.

I've now added an option to configure the image quality when resizing cover art via Adjust cover with Mp3tag v3.06f.
