The imageheight variable is not being passed through the XSLT. Looking at std.data_fields.xsl the imageheight variable is spelt 'iamgegeight'.
<xsl:when test="$item/@control='image_hyperlink'">
<!-- display this as a hyperlink around an image -->
<xsl:call-template name="hyperlink">
<xsl:with-param name="item" select="$item"/>
<xsl:with-param name="image" select="$item/@image"/>
<xsl:with-param name="imagewidth" select="$item/@imagewidth"/>
<xsl:with-param name="imageheight" select="$item/@imagegeight"/>
</xsl:call-template>
</xsl:when>
