* php5-imagick
*
* Provides:
- * Animated image support (for image/gif at least)
+ * Animated GIF resize support
*
- * Suggestions:
- * After enabling the ImageMagick plugin, you might want to regenerate
- * thumbnails for the newly support formats. This is easiest done with
- * a script in the GNU social-bundled scripts directory:
- * $ php scripts/clean_thumbnails.php
+ * Comments:
+ * Animated GIF resize requires setting $config['thumbnail']['animated'] = true;
*
* Bugs:
* Not even ImageMagick is very good at resizing animated GIFs.
+ * We are not infinitely fast, so resizing animated GIFs is _not_ recommended.
