How to store photo albums. Photographs and photo albums can be priceless family treasures. Humidity levels that are too high can be quite harmful to photographs. Humidity can cause pictures to stay together if they are maintained in stacks. The images may be destroyed if you try to separate them. Mold can cause photographs to curl and get ruined, just like books and documents. Photos must be kept at a consistent temperature, which is why they should not be kept in a basement, attic, or garage.
