Do you have something like a = ! a;

This would toggle a

Give „a“ a better name and make it global

You haven‘t comment on that.

What is your problem? That the changed image appears only during you hold the key?

Then you need to implement a boolean variable which you had and named a.

Did you delete it?

before setup boolean screen1bool=false;

Then on keyPressed toggle this variable as I have shown

Then outside keyPressed

if(screen1bool) {

}

Do you have this?

To make it faster you could do a new image in setup and depending on  
screen1bool use either the old or the new.

Since it doesn’t change every time

This would toggle on key b

```auto
if (keyPressed) {
  if ( key == ‘b’) {
    screen1bool= ! screen1bool;
  }
}

```

This you could do in setup ()

Here you make a new image img1 maybe you can copy it into imgNew and then load img1

Then you have 2 different images

Then you show one or the other depending on your boolean
