My digital indexing (mostly of non artistic day job work) is hard to get organized on.

I use ACDSee to print a contact page, with file nemes under each image and then scrawl notes around the remaining white space.
Images get downloaded and renamed for the day they are downloaded. Less than perfect, but it gives you some clue whe the snaps were taken, becuase they then to get dumped every few days, and the metadata can get you closer date if needed. Mostly they are construction progress documentation photos.
