Conditional statements not working…

First, thanks for creating such a simple and useful tool. I am trying to use conditional statements but they are being ignored. Here is an example. The img tag gets created with no image src even if I do not select a picture_url.

<div class="guest-post-bio">
<a name="author-bio"><h5>About the Author</h5></a>
<hr>
<div class="bio-content">
	[if picture_url] <img src="{{picture_url}}" width="100" />[/if]
	<div class="author-name">{{author_name}}</div>[if author_url] <div class="author-url">
	<a href="{{author_url}}" target="_blank">{{author_url_text}}</a></div>[/if]
	{{bio_text}}
	</div>
</div>

Are conditional statements only for the premium version?
