This can be done by using the shareware tool, GIF Construction. As a general rule, animated GIFs should be avoided as much as possible. There are many disadvantages of animation, here are some of the main points:

• Files are much larger and harder to transport
• Images take much longer to load into a page
• Causes heavy server traffic
• Most browsers don't allow for the loop function (allows an image to cycle through its animation sequence a specified number of times.
• The Netscape Navigator®(Versions prior to 3.xx) stop button does not work on animated images. They can cause slow run time for a PC, especially one with a pre-Pentium® chip.

On the other hand animated images can, if used properly, be a useful tool on a page.
