I am trying to use WED to make an Area 51 airport. I have an overlay in png form. I can import it into WED but when I try to input the coordinates of the four corners the image gets all skewed and finally ends up as a line when I input the second set of coordinates. I cannot figure out how to input all of the coordinates. I followed the manual and entered the points as P1, P2, etc. When I click on the corners of the image there are latitude and longitude already in the box that I am inputting the coordinates. I just overwrote the coordinates. Is there something I am doing wrong or something missing in what I have done? Thanks for any help. Regards, Bob.
