Loading Images in JavaFX

Question

Can someone please explain how to load images in JavaFX? Or point me to a tutorial?
All the answers I've seen use the __DIR__/imagename.ext to get the image. However, I have a decent sized project and do not want all my images in the same package.
src/package/FXClass
src/resources/images/imagename.ext
Please, what do I do to load 'imagename.ext' in the JavaFX class 'FXClass'?
Thanks.

__DIR__ is a URL. It could be an http:, jar: or a file: URL. If it's a jar: URL, then it's going to be something like:
jar:file:/my/project/path/dist/myproject.jar!/java/mainYou can use the java String API or java URL API to make a new URL of jar:file:/my/project/path/dist/myproject.jar!/java and set your ROOT variable to that.
This code from the media browser tutorial (from Constants.fx) does something similar. Notice the javafx.application.codebase property. When you run the tutorial from javafx.com, the codebase is http://javafx.com/docs/tutorials/mediabrowser/dist/ and all of the sample thumbnails and images are in thumbs and images directory (respectively).
* When running as an application or launcing in the browser from NetBeans,
* the sample images and thumbnails can be loaded from the jar file. But when
* deploying as an applet, putting all of these images in the jar file
* would bloat the jar file unnecessarily. In the applet case the images
* should be loaded from a server.
* <p>
* When running in the browser, the javafx.application.codebase property will
* be set to the applet's codebase URL. For the Media Browser tutorial, the
* sample images and thumbs are stored in directories rooted at this URL.
* The javafx.application.codebase property can be used, therefore, to locate
* the sample images and thumbnails.
package def CODEBASE : String = {
    var codebase = FX.getProperty("javafx.application.codebase");
    // If we don't have a codebase defined, or codebase starts with "file:",
    // assume we're running locally and load images from the jar.
    if ( codebase == "" or codebase.startsWith("file:") ) {
        codebase = __DIR__
    codebase
}
