Steps

Step 1. Open GIMP, and create a new image using File> New
- The size of the image depends on your purpose. Advertising banners range from 60 to 120 pixels high and 400 to 800 pixels wide. Different website programs and banner exchange systems will list their own requirements. For buttons, the height is generally no more than 40 pixels, and the width is usually less than 300 pixels. Separators, accents, widgets, etc. they have no restrictions, except maybe due to how much hard drive you have and how much bandwidth you will need to upload them.
- In this guide, we will select 200 pixels for the width and 20 pixels for the height, click OK. GIMP will give you a small, white rectangle.

Step 2. Make sure the toolbox is visible and the layer tools are also available
Each layer that we will create will be a "frame" in the animation.

Step 3. Use the bucket tool to paint the background layer a black color

Step 4. Use Filters> Render> Pattern> Grid, unlock the horizontal and vertical values by clicking on the little chain symbol between them, and enter 3 for the horizontal width and 4 for the vertical width, 0 for the intersection, 22 for the horizontal spacing, 18 for the vertical spacing, 2 for the intersection spacing, 1 for the horizontal offset, 0 for the vertical offset, and 6 for the intersection offset
Select the dark red color for the horizontal and vertical grid lines, click OK.

Step 5. Use the layer tools, right click on the background layer and select duplicate layer
Now right click on the layer called "background copy" and select layer properties to rename it to something simple like "frame 1".
Step 6. Use the same method to duplicate 16 more frames for a total of 16 frames plus the background frame

Step 7. This is a good time to save your work so far
Some animations lend themselves to different variations, and saving the frame will save you a lot of time. Use the internal GIMP format "XCF" for this file, as well as "AnimationTemplate.xcf".

Step 8. "Hide" all the boxes by clicking the Eye icon next to them

Step 9. Select Frame 1, Show Frame 1, and fill the box on the left with bright red

Step 10. Hide Frame 1, Show Frame 2, Select Frame 2 and fill the red box next to it with the same color

Step 11. Continue through all the squares, 'jumping' back to the left when you get to the far right

Step 12. Save this as a backup just in case you want to make some small changes "Backup Animation.xcf"

Step 13. Remove the "background" layer
Doing this at the end allows you to replace the errors and extend the animation if you choose to duplicate the background, but at the end it is usually not used for animation.

Step 14. Select File> Save As
.., name the file "Animation.gif", and click Save..
GIMP will ask you if you want to merge the visible layers or save as an animation. Select "save as an animation" and click "Export."

Step 15. The following image provides a place to save a-g.webp" />
The higher the number, the slower the animation.

Step 16. Finally, click save
