ie extra line using both tables and css

hello, the following code below creates an unwanted space (about 1px)
underneath my image using ie 6. this space does not show up in ff1. the
same results happen regardless if i use different images, or put my
image inside a table. any suggestions? thanks. aaron;

p.header {
border-style: solid;
border-color: #232D78;
border-width: 2px;

position:absolute;
top:50px

}

<p class="header">
<img src="myimage.gif" width="100" height="50" alt="mycaption"
border="0" />
</p>

.
