I've tried to set the appropriate files to chmod 777. I set data to 777. Look at it again and it is still 777. Open up data to set the others and when I go back and look at data it is back to 775. Can't figure why it is doing this.
I guess that would depend on how they setup there server. Can you upload an image and it is correctly processed at 755 permissions?
We tell people 777 permissions because on 99% of servers thats what permissions have to be to upload to the server. Now there are some servers that can allow uploads at 755 but thats server dependent.
