Hi guys, newbie here with a question.

So I'm trying to load images into processing while the sketch is running, with the images to be loaded specified by a message sent from a client. Basically, a message sent from max a max patch specifies what image to be loaded.

I'm trying to stay away from explaining the whole project, because then the conversation might get off topic, but I do have to say that the images can not be loaded in setup(), because the images have not been downloaded before the sketch is running (i'm scraping the images in max)

Anyway, here is a little sketch that doesnt work... can anyone help me?

import processing.net.*;

Server server;

PImage img;
String incomingMessage = "";

void setup() {
 size(500,500);
 server = new Server(this,5204);
}

void draw() {
 background(255);
 
Client client = server.available();

if (client != null) {
 incomingMessage = client.readString();
println(incomingMessage);
}
 if (mousePressed) {
 img = loadImage(incomingMessage);
 image(img, 100, 100, 100,100);
}
}
