Hi Minakshi,
Great knowing it and thanks for update.
Well I searched and found that you need to specify absolute path, don't know if it helps you. Just tried. Looking forward if any expert can help you which can update my knowledge as well.
<fo:block text-align="center" start-indent = "10.0cm"> <fo:external-graphic> <xsl:attribute name="src">C:/full path/</xsl:attribute> </fo:external-graphic> </fo:block>
Regards,
Padma
