I am a long term user of AbanteCart. It has always annoyed me that all icons how in the Resource Library Modal with the fa-code icon instead of the actual icon. Since my the issue has been corrected in the Media Manager and icons show as they truly are and my level of frustration reached a peak, I decided to fix the problem. Little did I know how easy it was.
A small edit to /admin/view/default/template/responses/common/resource_library.tpl is all it took.
On line 184 find:
<?php if ($rl['resource_code']) { ?>
<div class="thmb-prev thmb-icon">
<i class="fa fa-code fa-3"></i>
</div>
<?php } else { ?>
Change it to:
<?php if ($rl['resource_code']) { ?>
<div class="thmb-prev thmb-icon">
<?php echo $rl['resource_code']; ?>
</div>
<?php } else { ?>
Please consider making this change in future releases.
