Rollover Home-made Menu with onclick?

[imported_delta9]

Okay next problem

I've used rollover buttons in my own menu on the top, this has been added in the header.

<a href="#" onMouseOut="RestoreImg()" onMouseOver="SwitchImg('document.Display','document.Display','images/index2_11.gif')"><img src="images/index_11.gif" name="Display" width="314" height="151" alt="Display" border="0"></a>

Now i normally use different pages for each button, so when someone clicks on a button, i change the code for that page, so that the buttons stays 'clicked'.

But now i'm using Vbulletin everything is one page... does anyone know how to use code to get the same final view.

Menu is as follows:

- 1. Home (vbindex.php)
- 2. Gallery (Different script)
- 3. Adress Book (fixed version of memberlist.php)
- 4. E-mail Script (Vbulletin script)
