GifBuilder 0.4 is a scriptable utility to create animated GIF files on the Macintosh. It can be used manually to collect PICT, GIF, TIFF or Photoshop images or to convert QuickTime movies, FilmStrip or PICS files, or via AppleScript with other scriptable applications like clip2gif. Animated GIF files can be viewed with NetScape 2.0 and later, and probably other browsers now. GifBuilder is freeware, which means that it's copyrighted but you don't have to pay anything to use it.
