Thanks...but the problem is not with the permissions.. I just checked the access.log and found,
GET /static/buttons/academics_over.jpg HTTP/1.1" 200 2602
it means (error code 200 ) the file is corrupted. right?
I did ftp to the home folder as a user and then moved to www folder as root...
what next? do I need to load the files on server machine it self instead of ftp.. please let me know...
