Feature image crop across updates

Hi,

My feature image is crop to this
$image = gameaddict_aq_resize( $img_url, 817, 320, true, ”, true )

I can change this but it will not be preserved on the next update.

I will need to work on a fix for the dimension
1) That will work with new updates
2) Changing all pages that have this together
$image = gameaddict_aq_resize( $img_url, 817, 320, true, ”, true )

like

single.php
arhicve.php
author.php
category.php

Etc.

Kindly assist.
