How do I get rid of the outer edge?

I want to just cut the outer edge and stamp the inner sides. How do I upload the picture so it comes out correctly?

I want it like this but without the edge where the x’s are in the first photo

but when I upload it a different way it comes out like the 2nd photo.

can someone give me an example of the type of png i need to upload to acheive only stamp/cut outs on the inner parts, not the outer edges.
