Java.io.FilePermission Error

Question

So i am getting the following error when I attempt to upload a picure into my applet from my system. The applet has been signed and it does ask if I will accept the certificate. Yet I still get the error shown below. When I edit my java.policy file to allow all permissions it does work. So what do I need to do to make this work. Sort of useless if other can't upload stuff into my applet.
