so you want a link in the description? if so try using the plain HTML coding method as following,
if you want a text to be clickable then do:
HTML:
<a href="link goes here"/>text goes here that becomes clickable</a>
other wise if you want link to be clickable then do:
HTML:
<a href="link goes here"/>link goes here too</a>
Also for image i would guess file in app\themes\Peafowl\views\image.php try coping whole views content into override/views that way you will keep original version where it is and it will automaticly listen to copy in override path.
