How to make an animated gif image using GIMP

GIMP provides one of the easiest methods to create an animated gif if you are on a UNIX machine. The example above was made using the following steps:

• Create the series of images you will use to make the animation. Save them as Indexed Color GIF format images.
• Launch GIMP by typing,
  gimp
• From the File pull-down menu Open the first of your GIF images
• With the cursor over the first image, press the right button and scroll down the menu to open the Layers | Layers & Channels window.
  
  
• Press the New Layer icon on the Layers & Channels window
  
  Your Layers & Channels window should now look something like this,
  
  
• From the File pull-down menu Open the next GIF image.
• With the cursor on the second image press the right button and scroll down to Copy
• With the cursor on the first image press the right button and scroll down to Paste
  Your Layers & Channels window should now look something like this,
  
  
• With the cursor on the blue highlighted "Floating Selection" bar, press the right button and scroll down to Anchor Layer
  Your Layers & Channels window should now look something like this,
  
  
• Now is a good time to start naming the layers so you won't get confused. Highlight the Background layer icon and double click on the blue bar over the label Background. This will give you a dialog box to rename the layer to "Frame 1" Do the same with the New Layer and name it "Frame 2"
  Your Layers & Channels window should now look something like this,
  
  
• Perform the above steps with the remainder of your individual gif images.
• When finished, hold the cursor over the first image, press the right button and scroll down to File | Save As. Choose GIF as the File type, give it a new name and click OK
• In the Save as GIF window click Loop, a delay time (400 ms is a good starting delay), and One frame per layer (replace).
  
• When you open your saved image in a browser it will be animated. If the delay time is not appropriate for your images, just re-save with a different delay time.
