(Woozle writes) These are pictures from the week or so when Anna Nikola and I visited my aunt Mary Jo in Arizona. Most of them were taken August 6, 2000 (at least, that's the timestamp on the files, and evidence indicates they were offloaded on-site).
These were all taken with my first-ever digital camera, which came free with a subscription to Earthlink's dial-up service. It offloaded pictures over a serial cable, in .BMP format (though on close examination it's easy to tell that the actual data has been lossily compressed) at VGA (640x480) resolution.
The timestamp on these files is 2000-09-24, which is presumably when I offloaded them.
