you're nice image is all over the web ... without any credits.
just one example with commercial usage:
it looks like one of your images is uploaded and posted (cropped, text over it and without credits) on tsu, a new social network with a monetization concept and therefore the user makes money also with posting your photo. tsu pays 90% of it's revenue to it's users depending on their activities (posts, comments, followers). s3.amazonaws.com/tsu-productio…
you have to decide if you want to report this copyright infringement. many users on tsu post the work of photographers without permission and often without giving credits and no links and they make money like this.
you can join tsu e.g. by clicking on: www.tsu.co/ccomg_gmbh
after you have joined search for user "Kevin Hinkle" and click under the photo on "more" and then "report".
you can also email to firstname.lastname@example.org .
