Help with TH and CSS

[treeleaf20]

All,
I have the following code:

<table border="1" width="865">
<tr>
    <th rowspan="2" width="550" height="300"><img src="uploaded/1299272386.jpg" width="550" height="300"></th>
    <td height="190"><img src="uploaded/1299272386.jpg" height="190" width="300"></td> 
    </tr>
<tr>
    <td height="110" class="highlight"><div class="desc_text">BLACK and WHITE</div></td> 
</tr>
</table>

I then have the following CSS:

td {
background-color: #FFFFFF;
color: #000000;
}
th {
background-color: #FFFFFF;
color: #000000;
}
td.highlight {
color:#FFFFFF;
font-size:24px;
background-color: #F49855;
text-align:center;
vertical-align:middle;
}

When the first image is displayed there is like 5 pixels of white space underneath the image even though the image is the same size as the <th> height. Am I doing something wrong? Why doesn't the image fit perfectly? Thanks in advance.

You might try adding:

img {display:block}

to your css.
