To put one on your images, download a copy of Adobe Photoshop Elements (or a similar photo program that has a "place" feature).
Inside Photoshop Elements, open the car image first. Then using the "place" command, select the overlay image you like, and place that overlay onto the car photo. Move and size as you like, and then save the new image.
Pretty easy. May seem like a lot of steps, but once you do it once, it will be quick and easy every time.
