/* 
The refname array is used to build the on and off arrays.
For every image that will be a rollover, the has to be a name value in the tag.. like so
<img src="../images/howto.gif" width=119 height=25 border=0 alt="" NAME="howto">

To make the script more usable make all of the rollover images use this format
offimage = howto.gif
onimage  = howto_ov.gif

and give the image name value 'howto'
