I added a new property (title) to the Image media type but can't seem to get it work in the xslt.

<xsl:param name="imageFolder" select="/macro/imageFolder/Folder/@id"/>
    <xsl:if test="$imageFolder != 0">
      <p style="text-align: center;">
        <xsl:for-each select="umbraco.library:GetMedia($imageFolder, 'true')/descendant-or-self::*[@nodeTypeAlias='Image']/umbracoFile">
          <img style="width: 50px; margin-left: 5px; margin-right: 5px;">
            <xsl:attribute name="src"><xsl:value-of select="." /></xsl:attribute>
            <xsl:attribute name="alt"><xsl:value-of select="../@nodeName" /></xsl:attribute>
            <xsl:attribute name="title"><xsl:value-of select="./title" /></xsl:attribute>
          </img>
        </xsl:for-each>
      </p>
    </xsl:if>

Always comes out blank, Any ideas, know i must have missed something simple somewhere.
