PLEASE READ: As of 13/10/2011 I have added a creative commons "Attribution-NonCommercial-NoDerivs" license to all of my photographs. This means that if you wish to post any of them on tumblr, etc. you MUST give me credit (a link back to this flickr account or my blog), you CAN NOT edit the pictures in any way and they can not be used commercially.
If I see my photographs posted on your tumblr, blog, etc. without proper credit I will be sending you an invoice for using my work.
I don't want to sound rude but I have seen so many of my pictures on tumblr without credit, people claiming the credit themselves, etc. and its getting ridiculous. If you're going to use other peoples pictures, not just mine - but any other persons, you should give them proper credit or else buy a camera and take your own pictures.
Thank all you for understanding and so long as you provide credit I have no issue with you :)
