It's sad to see a cherished family photograph fade away or become damaged. Many times, these are images that just cannot be replaced. We certainly can't go back in time and take the photo again!
There are a number of things that can cause a photograph to lose its image: fading over time, water damage, creases and tears, etc. But these are things that can be corrected - usually with just a small amount of time involved. Of course, the worse the damage, the more time it may take to bring the image back, but it's rarely an impossible task.
