I am trying this Simon but get the error: "Failed to execute pipeline. org.apache.cocoon.ProcessingException: Failed to execute pipeline.: java.lang.RuntimeException: java.lang.IllegalArgumentException: Width (0) and height (0) cannot be <= 0"
I placed a width and height on svg:svg and svg:image but still get this error. Any clues?

There are the images embedded as base64-data elements too. The solutions was like Gerald, create a pipeline where you can extract the image. You will need to pass the document and an image-ID like: <map:match pattern="test/*/*.jpg"> <map:generate src="docs/{1}.wordml"/> <map:transform src="xsl/wordml2svg.xsl"> <map:parameter name="image" value="{2}"/> </map:transform> <map:serialize type="svg2jpeg"/> </map:match> You need an XSL-Stylesheet, which extract the image data and create a SVG-document. The SVG-image-element can hold the data as base64 endcoded xlink. Here is a snipped <xsl:match pattern="[EMAIL PROTECTED] = $image]"> <svg:svg> <svg:g> <svg:image xmlns:xlink="http://www.w3.org/1999/xlink"; width="3cm" height="2cm"> <xsl:attribute name="xlink:href"> <xsl:text>data:image/png;base64,</xsl:text> <!-- pass the base64 here --> <xsl:value-of select="yourBase64"/> </xsl:attribute> </svg:image> </svg:g> </svg:svg> </xsl:match> The SVG-serializer will generate the image. Inside your HTML you can generate a relative uri too, like <image src="foo/01111.jpg"/> if your page is foo.html from foo.wordml.
