&lt;p&gt;The system requires you to input the Product Option HTML code. This HTML code is used to display in the gallery when a customer wants to preview it before purchasing. There are two tags that are required by the system.&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;[MEDIAIMAGE]&lt;/strong&gt; &lt;br /&gt;The system will replace this tag with the actual media image.&lt;br /&gt;&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;[OPTION_ADD_TO_CART]&lt;/strong&gt;&lt;br /&gt;The system will replace this tag with the &quot;add to cart&quot; button.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;There is more information on this feature in the Product Options section of the main help menu.&lt;/p&gt;
&lt;p&gt;Click on the &lt;strong&gt;Submit&lt;/strong&gt; button to save the new Product Option Code.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
