That's why we have examples :
http://www.wicket-library.com/wicket-examples/images/wicket/bookmarkable/org.apache.wicket.examples.source.SourcesPage?SourcesPage_class=org.apache.wicket.examples.images.Home&source=ImagesApplication.java
If this doesn't help then do something like:
WebComponent img = new WebComponent("img");
CharSequence url = urlFor(new PackageResourceReference(Some.class, "some.png"));
img.add(AttributeModifier.append("src", url));
