the image is going to be viewed only onscreen. (The Document Size settings relate to print-
ing, which is covered on
Resizing for Printing
.)
Monitors are concerned only with the size of a photo as measured in pixels, known as the
pixel dimensions
. On a monitor, a pixel is always the same size (unlike a printer, which can
change the size of the pixels it prints). Your monitor doesn't know anything about pixels per
inch (ppi), and it can't change the way it displays a photo even if you change the photo's ppi
settings, as shown in
Figure 3-20
. (Graphics programs like Elements can change the size of
your onscreen view by, say, zooming in, but most programs can't.) All you have to decide is
how many pixels long and how many pixels wide you want the photo to be. You control
those measurements in the Pixel Dimensions section of the Image Size dialog box.
