After you've sorted all of your images into groups, decide on their destination. Here are a few ideas to get you started.
Photo boxes: Make sure the boxes are large enough for the photos you're storing. The Container Store has some great options to stash your stuff. And whatever you do, don't forget to label.
Albums: I love these binders from Russel + Hazel. All you'll need are inserts for organizing the photos.
Collection cabinet: Serious photo collectors might consider a collection cabinet for photo storage needs.
