Rated 5 out of 5 stars

The concept of centering the image was fine but adding a black background was completely unacceptable. This add-on is spot-on and simple, fixing a "bug" that really shouldn't be a bug. WHY fix something that aren't broken!
Thank you very much.

This review is for a previous version of the add-on (2.2.1.1-signed.1-signed).
