With this I have problem that then I need to take url from Image component
and put it into Link component:
<a href="#" <!-- <-this atribute --> wicket:id="anchor"
rel="lightbox"
title="">
<img style="border: 3px solid #DCD4A7;
padding: 1px 1px 1px 1px; width: 199px; height: 149px;" alt="" src="" <!--
<-and this atribute -->
wicket:id="image">
</a>
<!-- have to had the same url + .jpg at the end. Otherwise Lightbox won't
work -->
No problem make Image component as in example (my first attempt was same)
but not know how then take url from image component and put into Link
component.
