I just found out about Freepik – it’s a free online site that has town on vector images (essentially graphics). They even have some infographic templates that look pretty nice. Unless you pay for their pro service, you have to leave their logo on the designs somewhere, but otherwise you can download the graphics and even edit them if you have Adobe Illustrator or InkScape. Here’s one example I thought was pretty cool. http://www.freepik.com/free-vector/light-bulb-template-free-download_715739.htm
