How do you get rid of the white background of an image in paint?

Question

I have two images on paint I want to place on top of one another,but I can't because one has that annoying white box around it that blocks the other image. How do I crop the image so it has nothing around it/behind it and can be layed over top of other images?

Answer 1

When you paste the image there should be two icons to the left and one is to have a white border and the other is to make it clear.

It should look like the two bottom icons on the left in this picture:  http://www.actualtools.com/images/articl...

You want to select the last icon.
