    Adding default image to old content

    I have loads of old content with missing images. I would like to check if there is an image on each of them. If not, then i'll display a default image which sits on the ancestor page. Instead of adding images to each content manually, whats the best approach. I am trying it with xslt as follows.

     <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:msxml="urn:schemas-microsoft-com:xslt"
    xmlns:umbraco.library="urn:umbraco.library" xmlns:Examine="urn:Examine" 
    exclude-result-prefixes="msxml umbraco.library Examine ">


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

<xsl:param name="currentPage"/>

<xsl:template match="/">
    <xsl:variable name="mediaId" select="number($currentPage/heroImage)" />
    <xsl:choose>
          <xsl:when test="$mediaId &lt; 0">
                  <xsl:variable name="parentID" select="number($currentPage/ancestor-or-self::*[normalize-space(articleDefaultImage)][1]/umbracoImage)" /> 
            <xsl:if test="$parentID &gt; 0">
              <xsl:variable name="mediaNode" select="umbraco.library:GetMedia($parentID, 0)" />
              <xsl:if test="$mediaNode/defaultImage">
                            <xsl:value-of select="$mediaNode/defaultImage" disable-output-escaping="yes"/>
              </xsl:if>                                           
            </xsl:if>
          </xsl:when>
    </xsl:choose>
</xsl:template>

</xsl:stylesheet>

    Use an UmbracoAuthorizedApiController and the ContentService

    public class DefaultImageController: UmbracoAuthorizedApiController //Only works if you are logged into the backend
{
    public string SetDefaultImages()
    {
        var defaultImageId = 0;
        var contentService = Services.ContentService;
        var rootnodes = Umbraco.TypedContentAtRoot(); //Gets from the cache so fast to get all nodes
        foreach (var node in rootnodes)
        {
            foreach (var descendandNode in node.Descendants().Where(n => n.HasProperty("nameOfImageProperty") && n.HasValue("nameOfImageProperty") == false)) //replace by node.Descendants("Doctypealias")... if you want to filter
            {
                var editNode = contentService.GetById(node.Id); //Gets from the db = slow, so only do this if you want to edit.
                editNode.SetValue("nameOfImageProperty", defaultImageId);
                contentService.SaveAndPublishWithStatus(editNode);
            }
        }

        return "All nodes now have an image";
    }
}
