There are two ways to achieve this.
  1. You can create a global veriable and assign image data or image file path to that variable. Follow this page.
  2. You can write a singleton class and write get and set methods to access image data values of image file path. Follow this page.
I tried the global variable and it works ! I put global variable to every fxn that requires to call back the input :) Thank you Mr Pratik and Image Analyst !
