Anybody got ideas how to eliminate space between the bottom line of an image and the bottom line of a table?

using

<table border=0 cellspacing=0 cellpadding=0>
<tr>
<td>
<img src=pic.gif>
</td>
</tr>
</table>

gives unneeded and unexpected thin line between the image and and the bottom of the table, at least in my IE6.

Same phenomenon can be seen when you write text instead of placing an image, and there the extra space suits, but my goal is to place the image at the bottom of the table. Thanks for help
