I want to show an image that has been selected from a Media Picker. I have created an XSLT and a Macro.

I want to reuse the macro on several pages so I need to pass a parameter to my Macro with the property-id of the Media Picker. 

Something like this: (except from that $currentPage/$imageName is not working) 

<xsl:param name="currentPage"/>
<xsl:param name="imageName" select="macro/ImageName" />
    
<xsl:template match="/">
     
  <xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/$imageName, 0)" />
     
<xsl:if test="$media">
        <img src="{$media/umbracoFile}" />
</xsl:if>

</xsl:template>
