Hi Scott,
<ImageView image="..." /> translates to ImageView.setImage(String) (
where the string is a resource name as per ClassLoader.getResource(String) (

Thus, the path to your image must be found on your classpath.

Alternatively, you can prepend the string with "@" and use a relative path,
in which case the value will be converted to a URL relative to your WTKX
file, and Imageview.setImage(URL) will be called.

Hope that helps,
