Locking Image size

Hi there, 

I am trying to edit a template to no longer lock the image size of the logo section of an email template.  We are doing a rebrand and need the logo to be 160px width but as of right now it is locking the size at 97px. I tried adding mktoLockImgSize="false" but it didn't seem to work. Did I put it in the wrong place?

<!-- //Space_Section -->
<!-- Two_Column_Right_Image_Left_Content_Section -->

<table width="100%" border="0" cellspacing="0" cellpadding="0" mktoname="Two_Column_Right_Image_Left_Content_Section" id="Two_Column_Right_Image_Left_Content_Section" class="mktoModule">
<tbody>
<tr>
<td align="center" valign="top" style="padding:0px ${a2} ${h2};" class="em_aside20 em_pb25"><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td valign="top"><table align="left" class="em_wrapper" border="0" cellspacing="0" cellpadding="0">
<tr>
<td align="center" valign="top"><div class="mktoImg" mktoName="Logo Image"mktoLockImgSize="false" id="logo2"><a href="getfrontier.com/" target="_blank" style="text-decoration: none;"><img src="https://pages.enterprise.frontier.com/rs/044-JBX-919/images/Frontier_logo_Red.png" width="160" border="0" style="display: block; max-width: 160px;font-family: Arial, sans-serif; font-size: 16px; line-height: 24px; color: #F4080C; font-weight: bold;" alt="Frontier BUSINESS"/></a></div></td>
