I'm trying to get this film strip graphic to continusly wrap around the top and not stop after 1 revolution.

I tried duplicating the graphics and starting them further over but that doesn't work. How do I get around this? :(

Here is my code:

PImage h, h1, h2, h3;

int t;

void setup(){
size(750, 400);
smooth();
h = loadImage("topbanner.jpg");
h1 = loadImage("bottombanner.jpg");
h2 = loadImage("topbanner.jpg");
h3 = loadImage("bottombanner.jpg");
t = -h.width;
}

void draw(){


background(255);
image(h, t, 0);
image(h1, t, 350);
image(h2, t+750, 0);
image(h3, t+750, 350);
t += 10;
if(t > width) t = -h.width;

}

Thanks very much for your help :)
