I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

(Only some pages are loaded with full-sized images and those usually get removed after three months.) I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
2002 photos: This was the year I started the photo web site. It started to come together in August 2002, mostly as a way of allowing me to keep track of the pictures I was taking. It took awhile to add some basic bells and whistles (logging didn't get added until November) but it's been pretty much like it started out since then. Archaic but working, and free! Trips this year: Two weeks out west, one week in New York, and one week down south. Image quality isn't going to be very good for the first half of this year because these are scans of prints. Equipment this year: I took the plunge and bought my first digital camera. It was August 2002 and I bought an Epson PhotoPC 3100Z. While a nice camera, it had some quirks and bumping it would result in it being totally out of focus until you manually shut it down -- something which blurred almost every picture I took in New York City one day.
