If you have never checked out All Free Download stop what your doing and go check it out. This website is a never ending resource of vectors. Seriously, its one of the first two places I go when starting a new project. The best thing is if I like a particular layer, and not the entire image, I can grab just that layer. Of course I have to download the entire image and find the layer I like but all in all it saves me tons of time. So take a second and go check them out…you will not regret it.
