Hi Bart,

Try something along the lines of this:

<xsl:variable name="headerImageID" select="$currentPage/ancestor-or-self::*[normalize-space(HeaderImage)][1]/HeaderImage" />
<xsl:variable name="mediaNode" select="umbraco.library:GetMedia($headerImageID, false())" />

<xsl:choose>
    <xsl:when test="normalize-space($mediaNode/umbracoFile)">
        <xsl:value-of select="$mediaNode/umbracoFile" />
    </xsl:when>
    <xsl:otherwise>
        <xsl:text>/media/6899/recycled.jpg</xsl:text>
    </xsl:otherwise>
</xsl:choose>

Thanks Chriztian, but we're still getting errors, i think it's because the property exists everywhere, but it's only has a value on a few pages...

<xsl:variable name="headerImageID" select="$currentPage/ancestor-or-self::*[normalize-space(headerimage)][1]/headerimage" />

doesn't throw errors, but the second variable (MediaNode) does when i save the page...

This is the error i get when i save it:

Error occuredSystem.OverflowException: Value was either too large or too small for an Int32.

Nevermind, The solution was only declaring the medianode variable if data was available!

pretty much finished code:

<xsl:output method="xml" omit-xml-declaration="yes" />

<xsl:param name="currentPage"/>
          
<xsl:variable name="headerImageID" select="$currentPage/ancestor-or-self::*[normalize-space(headerimage)][1]/headerimage" />

<xsl:template match="/">
    <xsl:choose>
      <xsl:when test="$currentPage/ancestor-or-self::* [@isDoc and string(headerimage) != ''] ">
        <xsl:variable name="mediaNode" select="umbraco.library:GetMedia($headerImageID, false())" />   
        <xsl:value-of select="$mediaNode/umbracoFile" />
        </xsl:when>
        <xsl:otherwise>
            /media/6899/recycled.jpg
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

</xsl:stylesheet>

is working on a reply...
