Document Summary

Client: computer that is requesing to see/visit web page. Connected: computer is on all the ime, and connected to internet. Well maintained: take care of security and computer maintenance issues. Number of pixels across by the number of pixels down that a screen is displaying. Amount of space image takes up on the screen depends on size of image and current resoluion of screen. Depends on: size of the monitor in inches, current resoluion, but average pixels per inch usually around 72 ppi. Guaranteed that we see with the zoom lvl at 100 % will be about same size as on typical screen as if we decided to print again. But if want to print image, must be created at least at 300 ppi. Making it smaller, removes pixels and makes it crisper. On web, want the smallest ile size possible but want to display image at size appropriate for page.
