   It will be a little tricky although a fair bit of the trickyness
is in getting the line layout correct.  So if you don't have any
experience with CSS it will be harder.

   The majority of the text layout is done in the batik.gvt.text, 
batik.gvt.font
and batik.gvt.flow packages.  The flow package basically sits on top of 
the text
package taking the text and wrapping it to regions.  We already support
altGlyph which has some similarities to the image element, so I would 
suggest
looking at that and trying to extend it for images.

   Helder already provided some links for general documentation on Batik.
