Add Stroke to Placed Image or Photo

If you want to add a stroke to a placed image (File>Place) you can, but it's not as simple as choosing a color for the stroke. You could draw a rectangle the same size, but there's an easier way. With the placed image selected, go to the Appearance palette (Window>Appearance) and choose Add New Stroke from the flyout menu. Then from the Effect menu choose Path>Outline Object. Change the stroke color and weight, and you're all set.
