Thanks for the help guys.

I suspected Id need an extension function but hoped there was another
solution.

Thanks again.

Hi,

I've had a similar problem, I needed to test an image file exists and
if exists I needed width and height.

My solution is with Java, I can't find another way to resolve it.

<xsl:template name="file-exists" xmlns:file="java.io.File">
   <xsl:param name="filename"/>
   <xsl:value-of select="file:exists(file:new($filename))"/>
 </xsl:template>

<xsl:template name="image-size"

xmlns:java="xalan://javax.swing.ImageIcon">

   <xsl:param name="mida" select="'width'"/>
   <xsl:param name="filename"/>

  <xsl:if test="normalize-space($filename)">
    <xsl:variable name="imatge" select="java:new($filename)"/>
     <!-- Extract image file info -->
     <xsl:choose>
     <xsl:when test="$mida='width'">
      <xsl:value-of select="java:getIconWidth($imatge)"/>
     </xsl:when>
     <xsl:when test="$mida='height'">
      <xsl:value-of select="java:getIconHeight($imatge)"/>
     </xsl:when>
     <xsl:when test="$mida='mida'">
      <xsl:value-of
select="java:getIconHeight($imatge)*java:getIconWidth($imatge)"/>
     </xsl:when>
     <xsl:otherwise>
      <xsl:value-of select="-1"/>
     </xsl:otherwise>
    </xsl:choose>
   </xsl:if>
 </xsl:template>
