+          Digital images consist of a grid of square pixels.
+          Each image has a size measured in two dimensions, such as 900
           pixels wide by 600 pixels high. But pixels don't have a set size in
           physical space. To set up an image for printing, we use a value
           called resolution, defined as the ratio between an image's size in
           pixels and its physical size (usually in inches) when it is printed
           on paper. Most file formats (but not all) can save this value, which
