Even if you don't have a digital camera, it's still possible to upload a photo. You can use your traditional film camera and take photos of your rental. When you develop your film, ask your film developer to post your photos on a CD for you. Put the CD in your computer and locate the files on the CD. Use the link below for more details on posting photos.
More advanced users can use their cell phone camera or other mobile camera device to take photos, connect their device to their computer and then download the photos to their computer.
