I am trying to model this car and I got the blueprints and cropped each of the views and check that they were all within the scale of each other. I used these blueprints here
http://carblueprints.info/blueprints/porsche/porsche-911-gt3-2.gif
I didn't have to resize any of them just crop it so that each view is their own file and saved them in png format. So when I placed them in Blender they got resized and I don't know how to scale them within Blender.
This is what I'm getting so far.
The length of the car from the front is the same length as the car from the side view. I want to scale down the front view of the car but I do not know how. Also is there a way I can prevent blender from scaling so that when I import it, the images all stay in their respective sizes so I won't have to do any scaling in Blender.
