  By doing so,
you put the string value of the attribute @src in
the result tree.  So you
actually loose its base URI.  What you
want is to resolve its string value as
a URI, and against the
base URI of the node it is a value of:
<xsl:template match="html:img">
       <fo:external-graphic src="
url('{ resolve-uri(@src, base-uri(.)) }') "/>
    </xsl:template>

  But I've
just seen you are using XSLT 1.0, and those functions
are in XPath 2.0.  I do
not know in XSLT 1.0...
