ImageMagick library must use an extra key when working with GIF images.
See below:
function imageapi_imagemagick_image_resize(&$image, $width, $height) {
$extra = '';
if($image->info['mime_type'] == 'image/gif') {
$extra = '-coalesce ';
}
$image->ops[] = $extra . '-resize '. (int)...
I use the GD. ImageMagick not installed.
If you are sure that the case in the library then I apologize. Not even think to check it.
Be sure to check ImageMagick, thank you for your help.
