Before there was dialogs to indicate if current file is last or first. So in this commit, I added functionality to enable and disable forward and backward navigation based on if the next file is avialable or not and if the pervious file is avialable or not, respectively. ImageViewer: Refactor code and init data Data intialization was not happening properly, now I did Initializations properly so that navigation can work from the very first image.
