What do the file permissions have to be to upload files without using FTP (ie. installing a theme or plugin via wordpress). I have the folder of the installation chowned to my username and the webserver group and it's chmoded to 775 I think. I also have the wp-content file 777 i beleive. The reason why I can't use FTP is because this website is for someone else and I don't really want to make them an FTP account on the server unless I absolutly have to.
