Go to the Styles and Effects palette and choose Layer Styles/Bevels from the menus. Click on the "Simple Inner" bevel effect. Now switch from Bevels to Drop Shadows and click the "Low" shadow effect. Looks bad, doesn't it? Let's fix it by clicking on the tiny circled f on the layers palette. Change the following Style Settings:
Lighting angle: 130°
Shadow Distance: 1
Bevel Size: 1
(You may need to adjust these setting if you're working with a high resolution image.)
