Bit of HTML CSS help needed

Hi there peeps.
Ive been making a site with a table that loads content for various links, my table has been made partialy transparent. It all works perfectly fine but i want to know if theres a way to make my pictures opaque on their hover state.

<table style=“FILTER: Alpha(Opacity=65); border-collapse:collapse” border=“2” cellpadding=“0” cellspacing=“0” width=“95%” id=“AutoNumber2” bgcolor="#6699FF" bordercolor="#000066">

Thats my table, as you can see it has an alpha of 65%
This is my CSS links thingy…

<STYLE type=“text/css”><!–

I tryed this:

but it just stayed the same as the main table its in at 65%

Can i get around this?
