dpi is useful in commercial printing. Most printing companies prefer 300dpi images to make sure the images are printed nice and crisp. While on screen there is no difference between 72 dpi, and 300 dpi, on paper the difference can be obvious. This is the very reason I need to know the dpi, since the intranet application that I'm developing has to do with images that may be used for commercial printing. ----- Original Message ----- From: Gerry Danen I know. I can even create an image in Corel Paint Shop Pro at 600 dpi and it shows that. I still see only the 800x600 pixels. Where the dpi is useful is lost on me. Do you know?

Has nothing to do with the image, it just has x pixels by y pixels... On 2/15/06, Kim Christensen <kim.christensen@xxxxxxxxx> wrote: > On 2/15/06, Karuna <karuna.kgx@xxxxxxxxx> wrote: > > Thanks.
