For a while now i've been working on developing my first site. The main design has been tested on all modern browsers and they display the site brilliantly.  

Although I've been working on making the site more dynamic. I have three browsers. IE6 (which is isnt compatiable with the design alone) Mozilla 2 (displays the scripting and design brilliantly) and Opera 9

Now... Opera displayed the design perfectly last time. Although since i've added some javascript into it's fucked up.  

Opera will not display any of the images. nor will it display any CSS. it will run the javascript fine but thats about it. I've again made the HTML W3C valid.  

Like i say, mozilla firefox displays everything like it should do. IE partly displays the design minus the transparent divs and PNGs. Opera 9 does very little.

I'm confused because the design was 100% compatable with opera.  

I've uploaded it here:

can you test it on your browsers please? and post the results. And if you have any idea what could be wrong give us a clue.
