Yes, Gary, i have just tried to get image via absolute URL address and
succeeded. But i still want to be able to load images from applet via
getImage(String str). Possilby any access from applets to external files
is allowed only via URL addresses? Is there a way to know weather Java
program is run as applet or as application?
Thanks 4 help,
vladimir
