It would make more sense to use an array.
Code:

PImage [] buffer;
int myImage = 0;
void setup(){
  size(200,200);
  buffer = new PImage[10];
  for(int i = 0; i < buffer.length; i++){
    buffer[i] = new PImage((i + 1) * 20,(i + 1) * 20);
    rect(int(random(width)),int(random(height)),10,10);
    loadPixels();
    buffer[i].copy(g,0,0,width,height,0,0,buffer[i].width,buffer[i].height);
  }
  framerate(12);
}
void draw(){
  background(255);
  image(buffer[myImage],0,0);
  myImage = (myImage+1)%buffer.length;
}
 

What you're suggesting is common place in Flash as elements in a Flash movie tend not to have the capacity to be broken into arrays.

Got your array solution working, this was actually a parrallel image rotation attempt to the other posting you were responding to here http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Syntax;action=display;num=1131471481 so that solves both of those for me

thanks for your help, below is the code for anyone else who wants to use it.


public class rotateimage extends PApplet
{
 //initialise variables
 int v_width, v_height, v_screenwidth, v_screenheight;
 float v_increment = 0.00;
 PImage [] buffer;
 
 //setup function
 void setup()
 {
   //set stage size
   v_screenwidth = screen.width;
   v_screenheight = screen.height;
   size(v_screenwidth, v_screenheight, P3D);
   
   //set stage background
   background(0, 0, 0);

   //width and height stored as a variable
   v_width = 318; v_height = 256;
   
   //create an array with images
   buffer = new PImage[360];
   
   //load image
   PImage loadimage = loadImage("confused-black-dog.jpg");
   
   //centre all image placements
   translate(width / 2, height / 2);
   
   //loop through the buffer array
   for(int i = 0; i < buffer.length; i++)
   {
     //put an image in the buffer array
     buffer[i] = new PImage(v_width, v_height);
     
     //copy image in memory into image in buffer array
     loadPixels();
     buffer[i].copy(loadimage, 0, 0, loadimage.width, loadimage.height, 0, 0, v_width, v_height);
     buffer[i].updatePixels();  
 
     //display the image
     image(buffer[i], 0, 0);
     
     //rotate the image
     rotate(v_increment);

     //rotate this amount on next loop
     v_increment = 0.01754;
   }
 }  

}
