Getting an underscore on anchored images

Does anyone know why I am getting an anchor underscore under the images: http://i55.tinypic.com/1z5nj3k.png
... when using this code:
<TD align="center"><A href="'.$row['id'].'">'.$row['id'].'<IMG alt="" src="'.$row['id'].'/thumb.png" style="border: 0px; margin-top: 5px"></A></TD>
?

I can't. It doesn't exist yet.

Never mind, I just used two anchors... one for the text and the other for the image.
