                    {
                        this.sourceListView.View = View.LargeIcon;
                        this.SourceImageList.ImageSize = new Size(120, 120);
                        this.sourceListView.LargeImageList = this.SourceImageList;

                        DirectoryInfo dir = new DirectoryInfo("Images/");
                        var fileCount = (from file in Directory.EnumerateFiles("Images/", "*.bmp", SearchOption.AllDirectories) select file).Count();

                        {
                          this.SourceImageList.Images.Add(Image.FromFile(file.FullName));                 

                       }

                        for (int j = 0; j < this.SourceImageList.Images.Count; j++)
                        {
                            ListViewItem item = new ListViewItem();
                            item.ImageIndex = j;
                            this.sourceListView.Items.Add(item);
                        }
                }

           private void listView2_MouseDoubleClick(object sender, MouseEventArgs e)
                {
                    this.DestinationListView.View = View.LargeIcon;
                    this.DestinationListView.LargeImageList = this.DestinationImageList;                       
                    ListViewItem[] sel = new ListViewItem[1];
                    sel[0] = sourceListView.SelectedItems[0];
                    ListViewItem dragItem = sel[0];
                    DestinationImageList.ImageSize = new Size(256, 150);  // Want to more then this size that cover my whole panel.
this.DestinationImageList.Images.Add(SourceImageList.Images[dragItem.Index]);
this.DestinationImageList.Images.RemoveAt(DestinationImageList.Images.Count - 1);   

                    DestinationListView.Items.Clear();

                    for (int j = 0; j < this.DestinationImageList.Images.Count; j++)
                    {
                        ListViewItem item = new ListViewItem();
                        item.ImageIndex = j;
