How do i make the button link to another picture and that the new pic replaces it? Like turning pages in a book, that principle: Want it to be possible to go back and forward.

How do i do?

Any tips?

Use an array, maybe something like this example from processing wiki.

It's even easier because you don't need a timer just hook next and back button to the array.

PImage img;
String[] files;
int timer;
int nextimg;
void setup() {
size(400,400);
files=new String[3]; //some example images.
files[0]="medium.jpg";
files[1]="small.jpg";
files[2]="big.jpg";
nextimg=(nextimg+1)%files.length;
img=loadImage(files[nextimg]);
timer=0;
}
int nextimg=0;
String[] files;
PImage img;
int timer;
void draw() {
if(timer==0)
{
background(0);
image(img,0,0,width,height);
}
else if(timer==1)
{
img=loadImage(files[nextimg]);
nextimg=(nextimg+1)%files.length;
delay(1000); //this decides how long an image should be displayed
}
timer=(timer+1)%2;
}
