Subdomains and Static Files

[Weetabix]

After reading this (https://vborg.vbsupport.ru/showthread.php?t=223251) article, I have a few questions which I hope some guru can help me with. The article says to put css files on a different domain, yet the vB option for storing css as files says they must be stored in clientscript/vbulletin_css as CHmod777. How would I go about moving this to a subdomain, and how much of a risk is 777?

Likewise for images. Am I going to have to specify the new path for each individual file, or is there a way to point to the new images domain with a single command or option?

Apologies for the newb questions, it's a DAMN steep learning curve for the uninitiated.

Thanks in advance.

You should ask these questions in the Article thread. Princeton is much more likely to see your questions there than in a totally separate thread.

It was more of an article which made me think rather than an article I wanted to follow, as I wont be using a CDN or combining scripts. I referenced the article as it was similar to what I'm trying to achieve rather than explain from scratch.
