jeje, like Jeremias explains the new fop is able to resolve special
protocols like cocoon:// (I tested on the old one and it does not work
there). This solves the problem I guess for most if not all image links
since we can use cocoon pipelines to generate the image.

some right away, the others once we changed the pipelines, I
guess.

Which are the images that fail, because this should actually fix all
images? If not that can mean that we have another piece of code that is
changing the image linking (or the when test are matching).

In the skinned site

Thanks for helping on this.
