on select change image in wicket

[Layla Rashid]

Hi
I am new in wicket.
In a page I am showing a list of person. If I select a person , his information shows up including his picture.
I want to write a method , where, If I have no image it will show noImage.jpeg, If I have stored image it will show that image ,( it will change the image when I select that person from a person list ) and if don't have stored image but have twitter image it will show twitter image , when I select a person.
in my code , noImage and twitter image is showing up but I cannot display the stored image.

--------------------------------------------

WebMarkupContainer markup = new WebMarkupContainer("image");
markup.add(new AttributeModifier("src", true, new PropertyModel<Void>(
this, "image")));
add(markup);

----------------------------------------------

public ImageIcon getImage() {

ImageIcon p = null;

try {

if (selected == null) {
ImageIcon img = new ImageIcon("../noImages.jpeg");
p = img;
} else {

byte[] imageBytes = participantService.retrieveImage(selected);
if (imageBytes != null) {
BufferedImage img = ImageIO.read(new ByteArrayInputStream(
imageBytes));


java.awt.Image tagImg = img.getScaledInstance(80, 100, 100);


ImageIcon imgIcon = new ImageIcon(tagImg);



p = imgIcon;

} else {

if (selected.getTwitterUserAccount() != null) {
URL url = adminTwitterService.getProfileImage(selected
.getTwitterUserAccount());

ImageIcon img = new ImageIcon(url);
p = img;

}else{
ImageIcon img = new ImageIcon("../_img/images.jpeg");
p = img;
}
}

}

} catch (Exception e1) {
getSession().error(e1.getMessage() + "");
}

return p;

}
