We require that all picutures have a source or credit on tFS, per our Community Rules (link can be found at the bottom of every forum page). In the Community Rules you will find a link to the specific crediting rules which will go into more detail. To save you time, here is the link to the information you'll need.
Please post your source of this image in a new post ... if you took it yourself, that's all you need to say. Without a source or credit, we will have to remove this image ... and we sure don't want to do that.
