You can add picture to animated GIF as a separate frame. To update existing animation you can add frame or insert frame (frames).
To inset image you need to split animation by frames.
Then you have to specify position to insert picture for the inserted Image. Also you need to adjust positions of other images.
When you uploaded image it takes last position, so to add image to the tail of animated GIF image simple click "Create Animation" button.
To add image to the beginning specify the position as 1.
You can add Image (or insert Image) even if it's
an animation.
