Instead of doing like this,
ImageIcon img =new ImageIcon("src\\frame\\data\\heart7.png");
JButton btn=new JButton("Press Me", img); use this code,and then prepare the jar
try{
URL pathShell = null;
Object dummy = new Object(){
     public String toString() { return super.toString(); }
ClassLoader cl = dummy.getClass().getClassLoader();
pathShell  = cl.getResource("src\\frame\\data\\heart7.png");
image = new ImageIcon(pathShell);
JButton btn=new JButton("Press Me", imgage);
catch (Exception e) {}
