We have special archival-cardboard boxes (25x25x6 cm) with removable lids (25x6x4cm). However the 23x23 cm photos in the boxes are stored upright, and do indeed warp. Storing them on their sides would be better, but then the lids fall off the boxes (and prevent the boxes sitting flat) Keeping the photos flat somehow is a good idea. We group ours by run (with a labelled paper band around each run), and also turn the top photo in each run over so that when handling each run, fingers only come in contact with the backs of the photos, not the front.

What is a recommended means of storing hard-copy aerial photographs? He has a few hundred. Someone has suggested storing them on edge in a filing cabinet in a climate controlled room, but I thought that may cause them to warp. Are there any special factors to consider?
