Use scale to invert the image's direction. Note that this inverts the x axis so you'll need to make the x position negative to see it on the canvas. pushMatrix and popMatrix make it so that the scale only applies to the image and not all of the following commands.

```
pushMatrix();
scale(-1, 1);
image(getImage("avatars/leaf-green"), -120, 0);
popMatrix();
```
