Aligning with abolute position?

[MrApples]

I have an image, where in order to make it so it overlaps, I used this

position:absolute;
z-index:100

. It appears at the top left of the table data it is in, however I need it to appear at the top right. "right: 0;" cannot be used as that would put it at the right side of the entire page. align="right" does not work, valign on the table data does not work, and align right on a div forces the image to appear outside of the table. Everything I could think of has not worked.

Full code (just for reference I'm not asking anyone to look at this):

<style type="text/css">
img.logo
{
position:absolute;
z-index:100
}
</style>

<center>
<table id="Table_01" width=99% height="187" border="0" cellpadding="0" cellspacing="0">
	<tr>
		<!-- Buttons -->
		<td width="250">
		
		</td>
		<!-- Header (empty) -->
		<td width="524" height="159">
			<div>
				<img class="logo" src="/styles/7M-v1/new/defleft.png" alt="">
			</div>
			<img src="/styles/7M-v1/new/emptyleft.png" />
		</td>
		<td height="159">
			<img width="100%" height="159" src="/styles/7M-v1/new/emptymid.png" />
		</td>
		<td width="307" height="159">
			<div>
				<img class="logo" src="/styles/7M-v1/new/defright.png" alt="">
			</div>
			<img src="/styles/7M-v1/new/emptyright.png" />
		</td>
	</tr>
