Images uploaded with permission 600 and return 403 forbidden

[Amr Magdy]

Hi all

When I uploaded any image it uploaded to "/site/assets/files/xxxx" path  with permission  600 and return 403 forbidden when I tried yo access it or edit it

my config file now like this:

$config->chmodDir = '0755'; // permission for directories created by ProcessWire
$config->chmodFile = '0644'; // permission for files created by ProcessWire 

But after I upload new image I found 2 version of it : 

1. one named like :"orginal.0x260.jpg" with permission  644 
2. another one with orginal name with  permission 600

I tried to upload from another external PHP file to the same directory "assest/files" and it is uploaded with "644" !!!

Anybody can help?
