The photos

We need some photos of the parts of the car that we are going to modify, for example the front wing.
There are some photos of the R23 (I'm going to explain how to made the front wing):

We need a photo from a top wiew, other from the side and other from the front.

You have to save this photos in BMP format in order to can import it in ZModeler (if you want you can save it as TGA or PNG format).
If you want you can save the images in JPG format, but you have to install the ZModeler plug-ins from: ZModeler plug-ins.
These images must be squared and the dimensions must be: 256, 512, 1024 or 2048 pixels. I mean 256x256, 256x512, 512x512, 512x1024 ...

To do this open the photo of the car with your favourite paint program (The gimp, adobe photoshop, paint shop pro...) and then change the canvas size of the image (round up the size of the image to the nearest avaiable dimmension 256, 512, 1024 or 2048 pixels) and keeep the image centered. Finaly save it as BMP, TGA or PNG.

Now, in ZModeler you can load the image using the menu at the top-left corner of the view, then right click over the small rectangle and in popup menu choose: Bacgroung -> Image -> Load Image, then you will see the textures browser. Press Add... and search your image (the BMP, TGA or PNG) and click OK.
You have the image in the bacground. You can modify the background image with the image background control . Press this button and then with left click and drag with the mouse you can move the image and with right click and drag you can scale it.

You can see this in the following image (made with adobe photoshop):



Move the image and place it under the nose cone and the front wing of the original gp4 car. (how to import the car is explained in the next step: creating the mesh)



Now we can go to the next step.
