Why I have to create an Image in this way:
InputStream stream = MyPlugin.class.getResourceAsStream("shapes.gif");
Image image = new Image(null, stream);
try {
stream.close();
} catch (IOException ioe) {
}
If I write like this:
Image image = new Image(null,"shapes.gif");
will throw an exception?
thanks

Thank you!
