Unsigned applets can only download images from the server they were
loaded from. You will need to either copy the images to your server
and edit the applet tag to reflect the new address, or to sign the
applet. Michael Abramoff has a signed ImageJ applet at
http://bij.isi.uu.nl/applet.htmand instructions explaining how he signed it.

The plugins have to be added to ij.jar and you need to edit the
IJ_Props.txt file to add them to the Plugins menu. The plugins must
be at the root level of the jar file, along with IJ_Props.txt and
about.jpg. You can use the jar utility that comes with the Sun JDK to
extract the files from jar files and to build new jar files.
