The easiest way to get great art into your own stacks is to borrow pictures that already exist. The Home stack has links to several stacks that can inspire you. When you find a picture you like, copy it. Here's how:
• Use the Selection rectangle or the Lasso to select the picture. (Try selecting a frog or two now.)
• Choose Copy Picture from the Edit menu and then use the Browse tool to go to the next card.
