Just downloaded and used this product! It’s pretty awesome. One step processing. But the resizing needs a bit of changing. I was unable to just delete the default (1024×768) size and add in my own. I had to fool it first by deleting the last number (4) and then arrowing over to the 1 and changing it to an 8 and then deleting the 2 so I could get an 80×80 image from a 1024×768 sized image.
I love the way you can either overwrite the existing image or saving it as an image with a different name (same name with _bzzt added!).
