Support / Re: Thumbnails white background padding
« on: December 05, 2014, 07:26:18 PM »
I've figured it out, based on some code I found online.
If anyone ever needs this, here is the code.. I just change resize() function.
You'll need to maintain this across upgrades as it modified AbanteCart functionality directly.
core/lib/image.php
