This is a great pole, average monitor resolution is such an important variable in web design, i.e photos size. I wonder if someone has conducted a valid survey of these numbers. I go by looking at the Dell, HP etc web sites to determine what they are selling in their packages to decided what pixel size to make my website photos. I now assume the average monitor in the US is 1280X800, among other users mostly photography buffs in eastern Europe and else where in the world the resolutions maybe considerably less, I am in touch with some of them and the photos on my site are too large for their displays and they have to scroll to see the entire photo, which of course is a huge problem. I posted max 650 pix for my web photos but will change to 800 next update. I hope this works best on most monitors.
