Is it virtually possible to animate ANY image?

Say for example, I had my artist friend make an image in GIMP or Photoshop and he exports it to a png, and in this png image is a stick figure.
Could i just give this stick figure a skeleton (I think the term would be) to animate?

Is there a tutorial for this if so please link me.

Thanks for reading!

Hi,
Synfig can of course do it.
It is mainly vector-based animation but you can split your character into pieces and animate them with a skeleton.
Check wiki.synfig.org/Doc:Basic_Bone_Tutorial
Or you can purchase the official Training Pack which contains all the details :wink:
