Iam pretty sure that you must start with making a imagePlane, however I need help in applying the image file example jpeg or bitmap file on the plane, so I can apply curves lines ploys etc.
thanks

you can either make an imagePlane for your camera with 'view-imagePlane-import image' at the top of each of your camera's viewports and choose an image file there, or make a nurbs plane and import an image from the 'file' 2dtexture node option, when you click the checkered box next to your planes material colour option. I find typing and copying 'select imagePlane1;' or 'delete imagePlane1;' into the command line is the easiest way to select change your imagePlanes attributes.
hope thats what youre after
