Just a small error in the loadImage() reference page[ online and 0135 linux
docs], a PImage called 'online' is declared, but an image 'b' is called in
the draw() function.

[Also the String url link seems to be dead.]


PImage online;

void setup() {
String url = "http://mt0.google.com/mt?n=404&v=w2.61&x=9913&y=12119&zoom=2";
online = loadImage(url, "png");
noLoop();
}

void draw() {
image(b, 0, 0);
}

Thank you. It's fixed now.
