It's easiest with GIMP.
Open the head texture.
Right click the image and click on "filters".
Then, click on "animation", then on "spinning globe".
Then, when the animation comes up, right click again and press "filters".
Finally, click on "playback".
IF you want you upload this, save the globe animation, and upload it for free (no registration required) at
