Graphic design. Where to find high quality royalty free photos? - Part I

To start my walk in Seemit I'll write a series of post with different webs of banks of free images, some even, can be used commercially.

What can you do with a CCO (Creative Common Public License - Non-Proprietary License) image?
• Can be used for commercial and personal use
• Can be copied, distributed and modified

No need to ask for permission of any kind, that is, you can do with it whatever you want.

Using the images is a good way to improve a website, a post, a presentation ....

To start, I'll tell you about http://stokpic.com

Once registered on the web, we will be able to download 10 new photos every week.
We can use them for everything, but we can not redistribute them.
