It was the only picture that fitted, although it maybe first time a Volvo has been called a picnic table !
The site went live in May 2001 but there was no archive at that time, it came later. Actually I'm not sure why that particular picture is there, I've checked the original file and it does relate to that date. However, as far as I can tell there aren't any other pictures saved for 2001 so it may have been Mr.Webmaster testing the archive before it went live on 1-1-2002.
The picture descriptions weren't saved with the images until during June 2002.
