Image with parameters

Hi,

I have registered a shared resource with
IndexedSharedResourceCodingStrategy.
Now I want to add an image to one of my pages. But of course I need to
add a parameter to that image. How can this be done? I really can't find
any fitting constructor...

What I have so far is:



    ResourceReference imageResource = new ResourceReference(
"MyWellKnownKey" );

    HashMap<String, Object> map = new HashMap<String, Object>();
    map.put( "0", "myParameterIWantToAdd );

    CharSequence url = RequestCycle.get().urlFor( imageResource, new
ValueMap( map ) ); //that URL looks good! But what to do with?

    add( new Image( "image", String.valueOf( url ) ) ); //does not work



Where is

new ResourceReference ("MyWellKnownKey" , new ValueMap() );



Any hints?


Thanks,

Johannes

Aaaaaah!

Okay, found it....
It is exactly where it should be:

add( new Image( "image", imageResource, new ValueMap( map ) ) )


Thanks...
