It is possible to pass CSS properties to the composer function to change properties for images, for example to get them to cover the container (they are currenty set to max-width: 100%)
<table width=”<?php echo $td_width ?>” align=”right” class=”responsive” border=”0″ cellspacing=”0″ cellpadding=”0″>
<tr>
<td align=”center” valign=”top”>
<?php echo TNP_Composer::image($media); ?>
</td>
</tr>
</table>
