external viewer

A program that is launched or used by Web browsers (such as Mosaic) for presenting graphics, audio, video, VRML, and other multimedia files found on the Internet. It's sometimes referred to as a helper application. When you initially set up your browser, you configure the external viewers you want by associating them with file types extensions. This way, the browser knows what to do when these files are "clicked on."
