Whenever I give my Graphic Design for Developers talk, I'm often asked about good links for developers to learn the tricks of the graphic design trade.
Fortunately, dzineBlog has compiled a list of 50 sites that will help you become a better designer.
Some of the sites, I've recommended before and some are new to me, but all are excellent resources to help you bring out your inner designer.
