UnLoad image

How could I eventually Unload an image ... lets say with a mousePressed() or something like that..
is that possible?
or do I have to draw something on top of it to cover it?

if you are not running with noBackground() you can just stop drawing the image to the screen. for example:
if(!mousePressed) {
image(a, 0, 0);
}
if you are not refreshing the screen, you will need to draw something over it.

Thanks reas.
I was trying to have the image "UnLoad" once I clicked the screen... si then I did it like this:
BImage a;
boolean firstTime=true;
void setup(){
size(150,150);
background(255);
}
void loop(){
if(firstTime==true){
a=loadImage("box.gif");
image(a,0,0);
}
if(mousePressed) {
firstTime=false;
}
}

Here's a slighly nicer way to write that:
Code:
BImage a;
boolean unload=false;
void setup()
{
size(150,150);
background(255);
a=loadImage("box.gif");
}
void loop()
{
if(!unload){
image(a,0,0);
}
if(mousePressed) {
unload=true;
}
}
