Your subject line talks about Java. Java and JavaScript have about as much

User agent string detection instead of object detection with no provision
for most modern browsers.
It is not a good script. I strongly suggest you ditch it.

Most browsers let users block mucking about with the status bar - and with
good reason - its annoying and hides useful information from the user. I
suggest you get rid of that. Consider the title attribute for advistory
information.

..bmp files are highly inappropriate for use on the web. Try PNG, JPEG or
GIF.

The alt attribute is supposed to be a text replacement for the image, not a
tooltip. See my previous reference to the title attribute and try:
alt="Print References"

There is a distinct lack of anything between the links, this can cause it to
be difficult to tell where one link ends and the next starts (especially in
text only browsers). Try marking up the list of links as a list.

I'd suggest using <script src="..." ...></script> for including the
JavaScript. That will let the user cache it between pages and save
bandwidth (yours and theirs).

Probably having two elements with the same name and trying to reference them
by it.

Try it and see.
