Hi Ali,
Hmm, I think we misunderstood. You have an SVG document and you can
view most of it in the JSVGCanvas but the embedded png's don't show up.
In that case I think you need to send a sample document that shows the problem
for you because they should just show up (there are examples
included in batik like 'sample/tests/spec/structure/dataProtocol.svg'.
