A log of events that occur to an image file is kept. For example, if the image is e-mailed, printed, edited, etc., the event is recorded in the log. Consequently, a user can review the log and know what has been done with the image file previously. This log is created and maintained automatically. The log may be created when the image file is downloaded to a computer from a digital camera along with a specific instruction or intent of what is to be done immediately with the image file by the computer, e.g., e-mail or print the file. The log may also be created or updated subsequently as the image file is used. The log may be written into the image file or may be written in a separate file that is stored with the image file.
