Yeah but still even if he has the link and overwrites oncomponenttag
on that component, he has to get the content of the link tag
(everything between <a> and </a>) and be able to manipulate it. As far
as i know this is not possible from within wicket. The most likely
candidate getXmlTag() is private and even if that was not the case you
would have to resort to String manipulation because it does not have a
getChild(s) method.
But you might be able to do the same with some javascript. Just add a
header contributor which adds some javascript that will fetch the
first img childelement of the link and manipulate it any way you want.
