It’s not that I want the images to
be served from a .jar; I just want them to exist in a different place from the
code that is creating the Image component.
Suppose I have a hundred images I want to
be able to pass as a parameter to a page or panel – I have to do all this
a hundred times?

Location of image files
there are two parts to this if you want the image to
be served from a jar.
one. you have to create an initializer and bind the image as a package
resource:
public void init(Application application)
{
PackageResource.bind(application,
Tree.class, "blank.gif");
...
}
the Tree.class acts as a scope - the image is assumed to be in the same package
as the scope class.
the initializer is needed for clustering reasons. look at wicket.properties and
Initializer code in wicket package.
two. you must create a resource reference to your image:
/** Blank image. */
public static final ResourceReference BLANK = new
PackageResourceReference( Tree.class, "blank.gif");
after this you can create a url for the image in the package like so
RequestCycle.get().urlFor(BLANK);
hope this helps,

I am writing code that will be shared between two web

common code will be packaged in a .jar to be included by both web

One common component has a requirement to display an image whose
filename (or some other handle) it takes as a parameter. The images
that will be passed to this component to display are different for the
two web applications. Therefore, my image files must reside
separately
from the code which constructs the wicket.markup.html.image.Image
component.
The constructor for wicket.markup.html.image.Image can take a string
representing the image's file name. In all of the examples, the
image
file exists in the same directory as the component that creates the
Image component. If the image exists in some other arbitrary
location,
what are the rules for absolute or relative path addressing of the image
filename?
