need code help

Hi,

I have a galllery setup here

https://www.wildart.in

I have prettyphoto on my album pages here :
https://www.wildart.in/album/rufous-breasted-accentor/

Thing is someone click on image and it fetches large image in prettyPhoto.
Now I want to replace that to load permalink of that image.

The code is here that loads up prettyphoto popup.

<a href="<?php $img=get_sub_field('single_image'); echo $img;?>" class="lightbox" title="<?php  $size = getimagesize($img, $info);
if(is_array($info)) {
$iptc = iptcparse($info["APP13"]);
//print_r(array($iptc));
echo $iptc['2#120'][0]; } ?>" data-rel="prettyPhoto[1]">

Can anyone guide how can I replace so as the click on the thumbnail takes to permalink of that image ?

Sorry I am not a programmer just wish to make little mod’s myself which my fried has designed for me.

Thanks
