Getting width and height from Image obtained through ImageLoader?

Hi, I'm new to processing and playing around with an idea of making some generative art through google image searches (I used tumblr in this example). Everything works well except that I don't know how to get width and height info from the Image object obtained through ImageLoader (line 38), I guess it's a java image?

import at.mukprojects.imageloader.*;
import at.mukprojects.imageloader.tumblr.*;
import at.mukprojects.imageloader.image.*;

String apiKey = “apiKey";
String apiSecret = "apiSecret";

ImageLoader loader1;
ImageList list1;
Image img1;
int x;
int y;

void setup() {
  size(800, 450);
  loadImages();
}

void draw() {
  if (mousePressed) {
    x = mouseX;
    y = mouseY;
    newimage();
  }
}

//load images in list
void loadImages() {
  loader1 = new TumblrImageLoader(this, apiKey, apiSecret);
  list1 = loader1.start("copybara", false, 60 * 1000);
}

//get one image
void newimage() {
  img1 = list1.getRandom();
  try {
    image(img1.getImg(), x, y);
    //What I would like to do: image(img1.getImg(), x, y,img1.width/3,img1.height/3);
  }
  catch(Exception e) {
    img1 = null;
    println("no image");
  }
}
