Helpful (mostly free) design resources for software developers

I am a primarily a coder, and although I can implement design, websites and am creative from a technical perspective and have a eye for design, I don't really have the skills to originate graphic design, multimedia or user interface elements quickly whilst getting the development work done.

To help make things look good and professional, I have compiled a collection of useful design resources for developers who need some extra help with the design side of things.
