Hello @Bill_goo,

This works:

```auto
PImage bg;

void settings()
  { 
  println(pixelDensity); //What does this report?
  //pixelDensity(1); // Look this up.
    
  String urlString = "http://learningprocessing.com/code/assets/sunflower.jpg";
  bg = loadImage(urlString);
  
  if (bg == null) 
    {
    size(bg.width, bg.height);
    }
  else
    {
    println(bg.width, bg.height);
    size(bg.width, bg.height);
    }
  }

void setup()
  {
  }

void draw()
  {
  background(bg); // See reference
  }

```

Reference:

- [background() / Reference / Processing.org](https://processing.org/reference/background_.html)
- [pixelDensity() / Reference / Processing.org](https://processing.org/reference/pixelDensity_.html)

Try setting this and report back:  
`pixelDensity(1);`

It should have displayed as an image. Did it not?

`:)`
