Graphic Help Please

Hi, just starting out on this I have a full version (paid) of Easel and a free version of Fusion. I want to do a number of things but the first issue is getting a PNG graphic in to Easel so I can carve it.

So before I go all 3D, how do I get this image in so I can carve it?

Next step would be to do a 3D version but I know that is more advanced but if the first stage could be taken forward to the 3D stage that would save time and headache

Many thanks for any help
