GIF Construction Set for Windows
GIF Construction Set for Windows is an application to create, 
edit and display complex GIF files. It lets you fully exploit 
the block structure of the CompuServe GIF specification. Among 
its uses are creating web page animations and transparent GIF 
files; adding, editing and deleting comment blocks; adding non-
destructive text to images as plain text blocks; creating 
multiple-image GIF files; serving as a fully-compliant Windows 
GIF viewer application and providing a GIF viewer "helper" 
application for a World Wide Web browser or Mosaic client.
