Depending on how many photos you have, you can use one of the free cloud storage sites that are out there. I use Sugarsync to back up my photos. I prefer this site over others because they offer 5GB of free storage. Once you install the program on your computer, you can sync whatever folders you want with their cloud storage. When you get your new computer, install Sugarsync and you can then re-sync the files onto your new computer. They also have phone apps so you can sync or retrieve any of the files from your phone as well. The nice thing is that if you add, change or delete files, the changes are also made in the cloud.
