Hi Knute,
You wrote "If you jar up your Applet, access the
image file with; getImage(getClass().getResource
("fname.jpg"));

The applet is correctly jar'd along with the image
and shows as expected when the jar is opened.
I have tested to see that it does work.

I do not know what, if anything, goes into the ()
of getImage(getClass().getResource())
to exctract only the image from the jar by itself,
so that the image can go into
another program in the same folder.


im****t java.awt.*;
im****t java.applet.Applet;
im****t java.awt.Image;


public class ImageAppletBriefX extends Applet
  {
  private Image ioStream;
  private String errorMessage =3D null;
  public void init() {
    try
      {
      // the jar containing the image is
      //"TestLoadImage.jar"
      // the image file in the jar is "JBsm.JPG"
      ioStream =3D getImage(getClass().getResource());
      // << the line in question is above
      repaint();
      }
    catch (Exception netProblem )
      {
      errorMessage =3D "Could not reach image";
      }
    }


  public void paint( Graphics display)
    {
    if ( errorMessage =3D=3D null )
      display.drawImage( ioStream, 0, 0, this );
    else
      display.drawString( errorMessage, 10, 10 );
    }
  }

Thanks for your help up to this point

Hi Roedy,
I no longer desire to change the policy files.
your advice "That's a fairly dangerous thing to do.  That turns off
all security
for all apps anywhere" is well taken.
