CreativeIceDesigns shows all the steps it takes to give any photograph a nice, vintage look using Adobe Photoshop. The image must first be unlocked. You then select the grunge paper brush. Normally you should keep the aspect ratio of your image the same, but in this case, you should resize it to the same height as your paper surface. After changing the blend mode to multiply and adjusting the brightness, you then change the opacity and you'll have the "wrinkled paper" effect you're looking for. Watch this video and you'll know how to give your photographs that vintage look and feel.
