On all of our home computers, I will have the pictures, videos and documents re-directed to the home server by using the step above (changing the path). The reason for this (and folder re-direction) is very simple. It's easier to backup and recover when a bad situation occurs.
By using the shared folder for all pictures, for instance, when I backup my machine the backup will be much quicker (since pictures aren't on the local machine). In the case of a restore, again, much quicker. I am ensuring that the pictures are in a duplicated folder share so the backups are covered by the homeserver exclusively. . .
This method means all pictures can be in a single, centralized location. If something goes wrong, I don't have to worry about where the files are stored because they are all in one location. This just means that I may need to take additional steps to make very certain that my central location has rock solid backup/recovery capabilities. For me, that means connecting an external drive quarterly so that I can move pictures onto another drive that is not in the same location as the home server (in case of fire or something crazy with the homeserver).
