I have updated the JSFiddle, I hope this is what you need http://jsfiddle.net/bDBcD/3/
Made the following changes, made table width 100% and text-align:left for td.
<table width="100%">
<tr>
<td><img height="50" src="http://www.reduxpictures.com/newsletter/stock_oct13/Contrasto.png" style="padding: 0 0 0 0" width="174"/></td>
<td style="text-align:left;"><img class="logo" height="50" src="http://www.reduxpictures.com/newsletter/stock_oct13/Luz.png" width="174"/></td>
</tr>
</table>
