Is there any way to remove the border from my reference image?

Hi,

I'm making an assembly drawing for a circuit board, and I'm using .png files of my circuit board in the drawing. I insert them using insert > reference image and everything seems to work fine until I export it. The program adds another black border around the edge of the image, and it looks like my circuit board has two board outlines.

 

Is there any way to remove (i.e., not automatically add) the border from my reference image?
