-------- Image MIME type settings --------

Never edit settings/image.ini itself: an update replaces it. Put the settings you change in an override, which wins over the shipped file:

• settings/override/image.ini.append.php for every siteaccess,
• settings/siteaccess/<siteaccess>/image.ini.append.php for one siteaccess,
• extension/<extension>/settings/image.ini.append.php in an extension (read when the extension is active).

OverrideList #

A list of settings which override certain MIME types
The overrides can define allowed and disallowed filters
as well as extra filters.l

<?php /* #?ini charset="utf-8"?
# settings/override/image.ini.append.php
[MIMETypeSettings]
# an empty "OverrideList[]" first replaces the shipped list; without it the items are added
OverrideList[]
OverrideList[]=AnimatedGIF
OverrideList[]=LayeredPhotoshop
*/ ?>
