moving more than one image using a mouse

Hi All
I am looking for a program that will demo moving more than one image
with a mouse that is on a panel.

I have downloaded the program below and the first error reported was
the absence/can't find:
" import sim.util.*;"

I have jdk1.5.0_12 and Win xp

Is there a work around or some other help?
