About images, pixels, and resolution
Web photos are standardized to 72 pixels/inch (px). This is like "dots per inch" only on a monitor where each dot has a red, green, and blue phosphor (pixels). All pictures on this site are at the 72 px resolution. Format is JPEG usually set for maximum quality.

At 72 px/inch an image can be any width & height. Your monitor just can't display more at one time than it's setting--such as 800 pixels wide, 1024, 1140, 1600, etc. For example: This photo is 72px resolution and 400px wide X 291px high.

Web pages are usually 800 pixels wide, although 640 pixels is the maximum width of a printout of a webpage. That used to be the limiting size of webpages, but now that people have higher resolution monitors such as 1600 pixel wide LCDs the trend is to larger images.

Print images are saved in TIFF format, with resolution of 300 dots/inch (DPI). At such high resolution one then specifies size in inches. So a 300 dpi photo might be 5" x 7" or 8" x 10" , etc.
