If you're only loading the image from a directory on your hard disk (e.g. the C:\ drive), then you don't need to use an URL, you can simply pass a string to Toolkit.getDefaultToolkit.getImage(). From here

public static Image loadImg(String file) {    return Toolkit.getDefaultToolkit.getImage(file);}

If, however, you're intent on using an URL, all you need to do to resolve the return issue is to move the declaration of tmp outside the try/catch block.

public static Image loadImg() {    Image tmp = null;    try {        // load your image here    }    catch( ... ) {        // ensure that tmp is null    }    return tmp;}

String file = "C:\\mi_img.png";

If you need an URL object pointing to your image file, use the following:

// non-staticpublic java.net.URL loadResource(String path) {  return getClass().getResource(path);}// staticpublic static java.net.URL loadResource(String path) {  return ThisClass.class.getResource(path);}

Provided that you have a structure like the following...

- project directory  - src directory  - res directory

... you will have to specify a path like this:

String path = "/res/img_folder/img_file.jpg";

Hope this helps!

you have the 2 choices, however note that if you use a full path, like "C://myfolder/img.png" the game may not work on someone else's computer unless they place your game in the same place as you did and have the same folder names. If you intend to give your game to other people, you should consider doing it relatively to you game (e.g. palce sound with your games and instead of starting at C start in your game's directory)
