You could use GIMP to create a spinny head.
In GIMP, open your flat image of the head texture, go to
Filters > Animate > Globe, then save it as a .gif
After doing this, upload it to
www.imageshack.us or any other hosting website. Copy the link to that image and put it in these tags.

I've never done this before, but I just took 5 minutes searching about this and gave you an answer.
