You can put the photos in albums with multi-pocket bags. They stick to the photos and protect them from weather and bugs. An important thing to notice is these things should be kept away from sunlight, water, extreme temperature, changing humidity, etc. Basically, these stuffs are delicate and don't survive extreme natural conditions, bugs, rodents. destruction by chemicals or other substances.
I plan to scan all of my old photos and negatives and store them on my computer hard drive. I will also give a copy to my brother in case there is ever a computer crash or disaster so that they can't be lost.
