I am aware that versions of outlook will just display the first frame of a gif by default. However if you really wanted to go about doing a fallback image is the following correct?

<tr>
<td class="" align="" style="">
<!--[if (mso 12)|(mso 14)|(mso15)]>
<img src="staticImage.jpg">
<![endif]-->
<!--[if (mso 12)|(mso 14)|(mso15)]><!-- -->
<img src="gifImage.gif">
<!--<![endif]-->
</td>
</tr>

Is there a better way to do it? The idea is to make outlook 07, 10, 13 show the fallback image and other versions just show the gif.

Any comments would be appreciated
