How can I make a .cfg with two .png files?

I want to make a .cfg with one image for border and one for scanline overlay. Also I want to make it with adjustable opacity and scale. I just don’t don’t now the syntax, is it possible?

You can do it with one image… I don’t think you can with 2? Best route would be to make a shader preset with a nice scanline shader with a border image shader. Look at other examples in the cg shaders that have borders, like the handheld stuff. Scanlines as an image is horrible quality compared to what a shader can do.
