Applet.getImage() only starts a thread that starts to load the image:
To wait for it to load, use a MediaTracker or override the
imageUpdate() method.
For simplicity, just have a check:
if (i != null)
g.drawImage(...);
(IIRC, the default behaviour of imageUpdate() is to repaint when the
image has been loaded. But don't <Q> me on that. :-) )
