The course images are all jpegs as far as I know, approximately 1100 x 800 pixels I think, so they won't look much good when scaled up and as far as I know Nik, they are the same pictures as used in the flash game.
Exactly Scott. Changing the resolution of a frame does not mean you can change the actual original resolution of an image. What your tool does is resizing the image at a desired resolution, which is awesome!! Apart form that, if we are on to talk about resizing, scaling and cropping of the original picks, we will start to cry...however, for those who are trying to achieve the best image quality, i say that you can forget it cause matching a pixel ratio 1:1 on a 1080 monitor with a 1100 x 800 image is impossible. The only thing that remains is scaling.
