Now its duplicating images in listview...how could everytime someone adds image to it..that content before would be erased and new images would be added then..

It would be nice if the image collection had a method to clear itself.

private void btn_browse_Click()
{
    imageList1.Clear();

    // rest of your code here
    // but see below
}

this.listView1.View = View.LargeIcon;

this.imageList1.ImageSize = new Size(60, 60);

this.listView1.LargeImageList = this.imageList1;

this.imageList1.Images.Clear();
