Those images were generated using Merge.
Now that I've traced the template and made it into a simple drawing object, it's much easier to scale and overlay the template using OpenOffice Draw. Since it's an object, I was able to make the filled in area transparent thus making it easier to align on top of yer piccie.
Picasa,
OpenOffice, and
Merge are all free programs.
Using Picasa, straighten the piccie (if needed). I use Picasa because it doesn't distort the pixels.
Using OpenOffice Draw, open the aero template file.
Change view to Master.
Import car piccie and size proportionately (using the shift key).
Close Master view.
Using yer mouse, align the drawing object and re-size proportionately (using the shift key and drag any side/corner).
Change zoom view (Ctrl+ mouse wheel) and (with Picasa running in the background) take a screen shot (Alt+Print Screen). **This has a much better resolution than using the OpenOffice Draw export function.
Using Picasa, Save a Copy will make a copy from the BMP file to a JPG and then you can upload it.
Again...if you want the OpenOffice Draw file, send me a PM. It will have aerohead's piccie and both of my traces.
