This is a great plugin, however I can't find a solution for adding more sizes other than regular and thumbnails size.
I have a website which i display 4 different post thumbnails sizes. I would like to use single photo 4 all those different thumbnails using the same method used when using the regular wp post thumbnails but the authors of this plugin limited it to 2 sizes only.
any way of adding more sizes? what about using Boolean value of true for cropping?
