Hello,
I am using love.physics for my game, and that uses polygons for drawing, my question is, how would I make it an image?

You can use love.graphics.polygon:

Of course you'll have to map the coördinates of the polygon you are drawing to the ones in the shape.

If you mean an actual image, then you can just use love.graphics.draw to draw an image on top of the polygon shape.

NOTE: love.physics uses the center of an object as x,y and love.graphics uses the top left corner. So if you're seeing weird collision effects, probably the image and its shape aren't overlapping properly.
