Sorry didn't mean to mislead.

The miscreant in question badgered me to upload that particular one, she didn't create it.

The animated gifs can be created using imaging editing software such as photoshop.
You basically set up the animations by placing successive movements on separate layers and publishing the finished file as an animation setting a time delay for each frame (layer).

Photoshop also has a tween command which helps speed up the layer (movement) creation.
Gimp (opensource) is able to created animated gifs also, but the process is more long-winded as it lacks a tween function.

You can find tutorials outlining the procedure for each editor pretty much everywhere on the web.

Hmm my daughter has photoshop,maybe the start of a new hobby  :ideaw:
