Hi Wayne,

To get the trace output you need to set the key umbracoDebugMode to true in the web.config file.

My guess is you're probably iterating through a bunch of nodes, calling GetMedia() to get the images - if you're doing that, make sure to assert that the the image property (or what you've named it) has a value, before calling the extension. Otherwise, a single node with no image assigned will break the page.

You can do that in several ways, e.g.:

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/*[@isDoc]">
    <xsl:if test="normalize-space(image)">
        <!-- Call GetMedia(image, 0) here -->
    </xsl:if>
    <!-- Other stuff for this node -->
</xsl:for-each>

Or if you don't want to output nodes that have no image assigned, filter them right away:

<xsl:for-each select="umbraco.library:GetXmlNodeById($source)/*[@isDoc][normalize-space(image)]">
    <!-- Call GetMedia(image, 0) and other stuff in here  -->
</xsl:for-each>
