aligning an image vertically

In my code below, I would like to vertically align the image.gif to the logo holder class

I tried this:
bottom:0;
margin:auto;
position:absolute;
top:0;


but that didn't work?!

my code

<div class="item">
<div class="logoholder">
<a href="#" class="logo"><img src="/images/image.gif" width="131" height="78"/></a>
</div>
<div class="details">
<div class="name">company name</div>
<img src="/layoutimages/money.gif" alt="money" width="22" height="22"/>
<div class="amount">£4000</div>
<div class="bonus">100% Up To £4000 Bonus</div>
<div class="usa">Not Accepts USA Players</div>
</div>
<a href="#" class="sprite visit">visit us now</a>
<div class="company">this is a Powered Site</div>
</div>
