How upload *.ico file?

[quote author="noctrum" date="1273014172"]You have to add the ico extension to config/mimes.php. The only valid parameters in $config['allowed_types'] are extensions. icon|image|image/ico will all be ignored.[/quote]

I add to config/mimes.php to $mimes array variable next data:

Code:

...,
'ico'=>array('image/vnd.microsoft.icon',
             'image/ico',
             'image/icon',
             'text/ico',
             'application/ico',
             'image/x-icon'),
...,

and write "allowed_types" as:

Code:

$config['allowed_types']='gif|jpg|png|ico';

but already not work.

*.png/*.jpg/*.gif upload normally, but *.ico can't uploading.
