Multiple Image Inputs in Custom Shader

Is there a way to use multiple image inputs for a generative shader? I want to create a shader that uses three image inputs and an input from a camera or kinect to generate a dynamic image.

I have created the shader on interactiveshaderformat.com and it works there but when I try to import into Millumin, I don't know how to make the shader reference my images and kinect data.

Thanks!
