The following lists a number of freeware and shareware image viewing programs. The recommended viewer for both GIF and JPEG images is JPEGView. However, JPEGView requires Color QuickDraw. For Macintoshes without Color QuickDraw (those with the 68000 processor), use GIFConverter. GIFConverter is also the default viewer for TIFF images. SoundMachine is the recommended viewer for both AU and AIFF sounds, but it requires a minimum of a 68020 processor. If you have a 68000 Macintosh, try SoundBuilder. IBM PC users need to purchase QuickTime, and most UNIX workstation users cannot view files produced with QuickTime at all. So while QuickTime is universally available to Macintosh users, other platforms have limited or no access to these files. The MPEG format does support sound, but available MPEG viewers do not support this feature. SimplePlayer is the default QuickTime player; Sparkle is the default MPEG player. If your machine doesn't have a 68020 or above, you won't be able to view MPEG or QuickTime movies at all. If you don't have a PostScript printer or if you want to preview the document first, MacGS is an acceptable alternative. However, it requires a lot of hard disk space and often runs fairly slowly.Images

Animation
There two main formats: MPEG and QuickTime. Macintosh users can view both. QuickTime includes audio support. The MPEG format supports sound but the available viewers do not. If you are interested in including animations in documents you produce, you should know restrictions on other platforms. BijouPlay

PostScript
PostScript is a page-description language developed by Adobe Systems, Inc. Some complex documents on the Web are distributed in PostScript format. Usually, the best thing to do with PostScript files is to just print them out on a PostScript printer using Apple's LaserWriter Utility that comes with the system software. MacGS
RTF
RTF (rich text format) is a word-processing format developed by Microsoft to allow easy exchange of documents between word processors. Most of the common Macintosh word processors support RTF, but there are no public domain Macintosh programs available to display RTF files.
