Thank you , I found a way to solve this :
myLink.add(new Image("hexagramImage" , new PropertyModel(model , "index")
{
@Override
public Object getObject()
{
int index = ((Integer)super.getObject()).intValue();
return new ResourceReference(MyObject.class , "icons/byIndex/"+
index+".gif");
}
}));
It seems working now...
