see example below. I am trying to let the image occupy the whole image. But as you can see, there are still some background color showing. Any ideas to fix it? Thanks in advance!
Update: I am trying to do it on email html. So display:block
solution doesn't fit though.
<table border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td border="0" cellpadding="0" cellspacing="0" style="background-color:yellow;">
<img src="http://3.bp.blogspot.com/-oj_EN3P5Fjw/UR0AFZ_e-rI/AAAAAAAAAEE/vKTPlEEhzoY/s640/gnome.png">
</td>
</tr>
</tbody>
