Help with code

I'm having a problem upgrading my template for the new Blog app. Everything is working fine, except for image resize and cropping. Here is my code. What have I done wrong?

post.html code

<article class="h-entry">
    <h1>
        <a href="<perch:blog id="postURL" type="hidden" />" rel="bookmark" class="p-name">
            <perch:blog id="postTitle" type="text" label="Title" required="true" size="xl autowidth" order="1" />
        </a>
    </h1>
    <p class="meta">
        <time class="dt-published" datetime="<perch:blog id="postDateTime" type="date" label="Date" time="true" format="Y-m-d H:i:s" divider-before="Meta information" />">
            <perch:blog id="postDateTime" type="date" time="true" format="%d %B %Y" /> 
        </time>
        <perch:if exists="authorGivenName">
            by <span class="p-author h-card"><perch:blog id="authorGivenName" type="hidden" /> <perch:blog id="authorFamilyName" type="hidden" /></span>
        </perch:if>    
        <perch:categories id="categories" set="blog" label="Categories" display-as="checkboxes">
            <a href="archive.php?cat=<perch:category id="catSlug" type="slug" />" class="p-category">
                <perch:category id="catTitle" type="text" />
            </a>
        </perch:categories>

    </p>
    <perch:if exists="image">
        <div>
            <img src="<perch:blog id="image" type="image" width="540" height="360" crop="true" label="Image" order="4" />" alt="<perch:blog id="postTitle" />" />
