Picture File Names for Archiving

This page defines the prefered format for archiving original picture files (.JPG format).  The file name includes a code to indicate the image size (pixels), thus allowing for distinct storage of the same picture in different image sizes.  The format depends on whether the original image dates from the 20th century (ie. year 19xx), or from the 21st century (years 20xx).

Format for year 2000 onwards“ymdd_xxj.jpg”.

Format for years up to 1999“yymdd_xj.jpg”.
