I am usually very busy and just don't have the time. When I get "free time" I have a very long list of things that I need to get done, so I do those. When I get too exhausted to work, too caffeinated to sleep, and have a few free seconds, I update the site. In that mental state it takes a lot of effort to put thoughts into English and make it readable. I would like to update more often, and am trying to do so.
I put the highest resolution version of the image that I have in the Master section linked from the main Pictures page. Those images will be the raw images from my digital camera or from having scanned in existing photographs. They should be quite large enough for backgrounds, high resolution enough for printing on a photo printer, and detailed enough for blackmail.
I will go back and correct spelling mistakes or web links. But I do not change the content (usually).
