Combining multiple animated gif files?

Question:

Combining multiple animated gif files?

What program do I use to insert three animated gifs on to a blank canvas. I have made three animated gifs, first animated gif is a bouncing ball from bottom of screen to top of screen. Second animated gif is arrows coming from off screen left side to off screen right side and the third animated gif is spinning stars coming from off screen right side to off screen left side. I want these three animated gifs on one canvas so I can save all three as one animated gif. Any suggestions of what program to use. Thank you.

"The GIF file format allows you to combine multiple GIF images into a single file to create animation. There are a number of drawbacks to this functionality, however. The GIF format applies no compression between frames, so if you are combining four 30-kilobyte images into a single animation, you will end up with a 120 KB GIF file to push through the wire. The load is lightened somewhat by the fact that animated GIF files stream to the user, so the frames load and play even before the entire file is downloaded. Another drawback of GIF animations is that they are an imposition and a potential distraction. Because there are no interface controls for this file format, GIF animations play whether you want them to or not. And if looping is enabled, the animations play again and again and again. GIF animations are rarely used in a meaningful way, and generally distract readers from the main content of the page. If you are using GIF animation as content — to illustrate a concept or technique where animation is really required — use the technique sparingly."

So I would recommend that you just create all 3 in one. www.Glickr.com lets you upload ten images and make a gif. There are probably some other online sties.
