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 name="image-size"
   <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:when test="$mida='width'">
      <xsl:value-of select="java:getIconWidth($imatge)"/>
     <xsl:when test="$mida='height'">
      <xsl:value-of select="java:getIconHeight($imatge)"/>
     <xsl:when test="$mida='mida'">
      <xsl:value-of select="-1"/>
