Animated GIFs With GIMP

Animated GIFs have been a popular image format amongst web designers for years. Perhaps this is due to the ease of creating an animation using this format.

What Is An Animated GIF?

An animated GIF is simply an animated image, saved as a GIF. The animation occurs due to multiple "frames" being present within the image. Each frame represents a different image within the image. When the image is displayed, it runs through each frame, one after the other. This can occur quickly or slowly (as specified by the designer).

Here's an example of an animated GIF:

In the above example, there are four frames.

1. The first frame is simply a photo
2. In the second frame, the word "Keep" is added
3. In the third frame, the word "Earth" is added
4. In the fourth frame, the word "GREEN" is added

Once the animation reaches the end (after the word GREEN), it starts again. This is called a "loop" - as it loops over and over the same animation. If it wasn't looped, it would stop at the fourth frame.

Creating Animations With GIMP

GIMP provides a couple of ways of creating animated GIFs.

1. Using Script-Fu. Script-Fu is GIMP's scripting extension. It allows you to apply filters to your image that have an animated effect.
2. Using Layers. Layers provide you with more options for your animated GIFs. Each layer becomes a different frame in your animation.

Many GIMP users don't actually realize that they can use GIMP to create animated GIFs.
