This add-on does not work on big images, which is what it is supposed to do, no? Images get converted to garbage when the original has more than 3Mpx (2000x1500), i.e. most images that come out of a modern camera. I tested this by scaling the same image, and only when I made it small enough did it pass. When I then resized it to make it bigger it once again got messed up. PLEASE CORRECT THIS as this is a very useful extension to have when it works !!!!
This review is for a previous version of the add-on (3.1.1-signed).
