How do I make a tween that changes the object's size?

[saving_is_for_nerds]

I'm making an animation with very specific graphics, so I created the files in a separate art program. However, when I try to tween with it (Classic tween, just changing the size and rotating) it doesn't work. How can I make a rotation and/or resizing tween using custom image files?

Hi.

You should turn your imported artworks into symbols, create keyframes and apply tweens.

Can you describe exactly what you're doing or provide some screenshots?
