Thank you Bob, that was the exact place I need to add the code I wanted.
It works perfectly now.

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=classlazy/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
noscriptimg 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?)
