Here is a good answer: Take the SD card out, put it in your Chromebook or USB card reader, and then upload the pictures to Picasa under an album named for the date/trip so I don't have to name them all, and then leave them until they are required again. Presume you already have installed the Picasa extension from web store and have an account.
