How do you fade out Images?

HannahD

So I already have 4 pictures done from a code someone showed me, but i can't figure out how to add more to it. Any helpers? I'm very new to processing!

PImage img;
PImage img1;
PImage img2;
PImage img3;


int transparency1;
int transparency2;
int transparency3;




void setup(){
  size(640,480);
  transparency1 = 255;
  transparency2 = 0;
  transparency3 = 0;
  img = loadImage("girl.jpg");
  img1 = loadImage("field.jpg");
  img2 = loadImage("bubbles.jpg");
  img3 = loadImage("balloons.jpg");

}
void draw(){
  background(255);
  tint(255,255,255,transparency1);
  image(img,0,0);
  if(transparency1 > 0) {
    transparency1--;
  }
  tint(255,255,255-transparency1);
  image(img1,0,0);

  tint(255,255,255,transparency2);
  image(img2,0,0);
  if((transparency1 == 0) &&(transparency2 < 255)){
    transparency2++;
  }
  tint(255,255,255,transparency3);
  image(img3,0,0);
  if((transparency2 >0) && (transparency2 ==255)) {
    transparency3++;
  }

}
