I don't know if this is the right place for this.
I am trying to access a file and I get this.
You don't have permission to access /newad.jpg on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
any help is appreciated.

It means that the user that the server runs under does not have read permissions to that file.
chmod 644 filename
to fix this, or can be other issue like blocked file with htaccess, or other settings.

I figure out the problem it had to do with the .htaccess file.
thanks for your help though.
