Thanks for your reply
my website main directory is laralapa.com so ,I choose the img folder in the same directory.
Do I have to choose another img folder to make changes in permissions ?
I am confused which folders should I write permissions.I contacted my hosting provider (quoting them as under)
"hi
as it is a windows server and permissions like 777 or 755 belong to Apache server are not there, and are controlled by IIS
Pl ask them what it should be on a windows server with latest Plesk 12 control panel "
Thanks
Danny
