DPI isn't out of date, Ysvry, it's very important to the printing process and the key to good prints. Don't try to confuse GoneDigital, please. You can NOT change DPI without changing your image size, GoneDigital. DPI is just a description of how detailed your image will be for a given print size. So, an image that is 1,000x600 will print at 100 DPI on a 10x6 card, or at 200 DPI on a 5x3 card. If your image is a a standard 8.5"x11", then 300 DPI would be 2550x3300 pixels. Like the others said, it's best done with the "render to disk" function...
