Grow thumbnail to main image and then back

Question

I am wanting to modify the dynamic photo Gallery to Grow each thumbnail to the main image position.
When another thumbnail is selected it should shrink back to it's  original position before the Grow.
When another thumbnail is clicked it does the same grow effect and takes it place of the main image and the first thumbnail shrinks
and returns to where it's original thumbnail positions was.
It would have to be constructed so the thumbnail that is clicked stays and a duplicate of it grows from it's current position.
If someone could help do this in stages so I can understand how the code initializes, this would be greatly appreciated.

Use a Seperate Thread to do it:
Runnable r = new Runnable() {
    public void run() {
               int k=tree.getSelectionRows()[0];
               DefaultMutableTreeNode node = (DefaultMutableTreeNode)tree.getLastSelectedPathComponent();
                            if(node.getNextSibling()!=null)
                                 tree.setSelectionRow(k+1);
                            else
                                 tree.setSelectionRow(k-1);
                            sleepe(k);
public void sleepe(int i){
                     try{
                            Thread.sleep(1000);
                                 }catch(Exception e){
                                     e.printStackTrace();
                              tree.setSelectionRow(i);
    }Then start this thread in a mouse click event(or any other similar),but not in TableSelectionListener because >>if the current selected row is 1 then it will execute the valueChanged method of TableSe..li. and we set the selected row to 2 then again it will execute the valueChanged method of TableSe..li.It will repeat till something,or in error.
tree.addMouseListener( new MouseListener(){
public void mouseClicked(MouseEvent e) {
                   new Thread(r).start();
public  void mouseEntered(MouseEvent e) {
public  void mouseExited(MouseEvent e) {
public  void mousePressed(MouseEvent e)     {
public  void mouseReleased(MouseEvent e) {
  });Note:it worked perfectly for me. So add all the above in the right place and import necessary.It will execute perfectly.
