I just wanted to know how to i add functionality to prev and next arrow images to show next and previous images with jquery.

use prev and next to find an element before/after the current one and activate it. You will need to decouple element activation code from the onclick event.

you're using

 $(...).click(function() {
     code
     that 
     activates
     "this"
 });

but now you need to reuse the activation code, so decouple it

 activate = function(elem) {
     code
     that 
     activates
     "elem"
 }

 $(img).click(function() {
     activate(this)
 });

 $(#left).click(function() {
     activate(currentElement.prev())
 });

 $(#right).click(function() {
     activate(currentElement.next())
 });
