TIP: Many graphics programs provide a feature that will resize a
graphic. An easy way to create a thumbnail image is to first create

graphics program to create a version of that image that is 25% of
the original size. Save the thumbnail version using a different
name.

TIP: If you are using a graphics program that supports a posterize
feature for specifying the number of tonal levels per color
channel, set the number of tonal levels per channel to 40 (40 red
X 40 green X 40 blue = 64000 colors). This is as close as you can
posterize to 65535 colors without exceeding the maximum.
