drawing with image

estuary24

I want to create a program where the image is controlled by the mouse cursor so when the user clicks the image pops up in that location on the screen. The problem I am trying to fix is that the image following the mouse is continually drawing images creating a trail behind it. I can fix that problem with background(100); or drawing a rect(0,0, width, height); , however that would cover up the images purposely created by the user when he or she clicks on the screen. The idea is that the user can create images in a desired location, with the mouse cursor "carrying" that image in any location. There is an image with mouseX and mouseY coordinates, but that image need not create a trail of images behind it. So this is what I'm trying to fix. Is it possible to do this ? and can someone please give suggestions.

PGraphics pg;

void setup(){
  size(400,400);
  pg = createGraphics(width,height);
  pg.beginDraw();
  pg.background(0);
  pg.endDraw();
}

void draw(){
  background(0);
  if(mousePressed){
    pg.beginDraw();
    pg.stroke(0,255,0);
    pg.line(mouseX,mouseY,pmouseX,pmouseY);
    pg.endDraw();
  }
  image(pg.get(),0,0);
  fill(255,0,0);
  ellipse(mouseX,mouseY,20,20);
}
