Hi David,
No need to call 'process.image' again. Since you have already copied it to your
customization layer, you can just add the extra element there. Put it after these
lines:
<xsl:otherwise>
<xsl:copy-of select="$img"/>
</xsl:otherwise>
</xsl:choose>
which is just before the <map> element would be output for an imagemap, or at the very
end of the template.

Subject: [docbook-apps] Customizing the process.image template
Hi,
I'm using the [Lazy Load](http://www.appelsiini.net/projects/lazyload)
JQuery plugin to help out on some image-heavy docbook articles. I
basically just copy/pasted the process.image template to my
customization later and made these changes ("data-original" was "src"
and the last two attributes are my additions):
<xsl:attribute name="data-original">
<xsl:choose>
<xsl:when test="$img.src.path != '' and $tag = 'img' and
not(starts-with($output_filename, '/')) and
not(contains($output_filename, '://'))">
<xsl:value-of select="$img.src.path"/>
</xsl:when>
</xsl:choose>
<xsl:value-of select="$output_filename"/>
</xsl:attribute>
<xsl:attribute
name="src">../img/common/placeholder.png</xsl:attribute>
<xsl:attribute name="class">lazy</xsl:attribute>
It works just fine, that's not the problem. I want to make it degrade
gracefully (without JavaScript, only the placeholder image is
displayed). The way the plugin author recommends to do so is the place
an alternative in a <noscript> tag after the image, like this:
<img class="lazy" src="img/placeholder.png"
data-original="img/realimage.jpg">
<noscript><img src="img/realimage.jpg"></noscript>
My question is where/how in the process.image template should this
redundant image be added? (Perhaps I need to call process.image twice in
the imagedata template, then have some sort of condition in
process.image to determine whether to swap "src" and "data-original"?)
