I managed to upload an Odoo 10.0 instance to Amazon EC2 and since I'd been adding custom addons to FTP, it seemed that static images were not visible to browser.

For example:

http://mysite.com/backend_theme_v10/static/description/icon.png <--- (installable addon but image could not be viewed)

https://drive.google.com/open?id=0BwUx6dWaBFLUeXhjWE1DNFVhalE (actual image)

Is there a config that I missed?
