They load from the center which I find superior to side or top loading sleeves

These load from the side and the pictures never fall out

These are the best for 4x6 photos - loads on both sides from the center - easier to load and don't have to worry about them falling out.

To my surprise, these have been the best and are thankfully the cheapest as well!These load from the middle of the sheet

This is great because photos have a tendency to slide out of top-loading pages

I get true digital pictures and they won't stay in my top loading pages
