So the time has come that I'm developing my first wordpress theme. Since I'm testing on my localhost and I wanted to be able to install plugins and upload images, I changed the permissions of the theme's content I'm working on to 777 by editing them in the get info respectively. However I'm unsure to what settings I should change those settings when the theme goes live. As I've read that 777 imposed quite a security issue. Should I do that in get info again or is it better to do it in the ftp client?
