In my wicket application there are pages for users depending upon their role and on different criteria. In my database I am storing the path of image to be used as a background for that user. Every user has a unique page. I know I can add read image if I do something like this :
<img wicket:id="img">
and corresponding to this I am writing the code which will get image for me .
But how can I set the image as body background dynamically .I am pretty much new to wicket .Can anybody have a clue how to do that ?

In your page you can do it with some header contribution:
@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.render(CssHeaderItem.forCSS("body{ background-image: url('" + getBackgroundBodyImagePath() + "');};", "uniqueBodyBackground"));
}
Or you could assign a wicket id to your <body> element and add an AttributeModifier like this:
@Override
protected void onInitialize() {
super.onInitialize();
bodyElement.add(AttributeModifier.replace("style", "background-image: url(" + getBackgroundBodyImagePath() + \"');"));
}
