HTML: Understanding graphic size and resolution

This entry is part 28 of 34 in the series HTML

A graphic image’s resolution is the number of unique dots, or pixels, it contains.

Resolution is expressed in width and height, always in that order.

For example, an image that is 800 x 600 is 800 pixels wide and 600 pixels tall.

A graphic’s file size–how many bytes the file will take up on disk–has a direct relationship to its resolution. ┬áThe more pixels in a graphic, the larger the file.
