So, I have my CD of pictures from the photographer and I want to make sure that I have every single picture from the wedding for years to come. And by that I mean that fifty years from now, I'd like to be able to still have all 1100 of these pics in digital format. Obviously, media formats come and go so a CD probably isn't the best option for storage. How would you suggest I back up and store these images so that they last for fifty years?
