How to Distribute Trees in Specific Areas

I have a plane which is my terrain with an image mapped on it. I want to place trees in specific areas of the terrain.

  1. I could weight paint on that plane in specific areas but the problem is I can’t see the image in weight paint mode so I can’t tell where to paint the weights. Is there a way to be able to see my image while painting in Weight Paint mode?

or

  1. Is there a way to use an image (.jpg) to distribute my trees. So for example in Vue I can use an image map to distribute my trees and then my trees will only go where the black part of the image is.
