Hi <insert name here>,
Nearly all my flickr images are automatically available to use under a cc by-sa licence. You can see the details in the photo page by clicking on the licence. Basically:
You are free:
to Share — to copy, distribute and transmit the work
to Remix — to adapt the work
to make commercial use of the work
Under the following conditions:
You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).
Share Alike —
If you alter, transform, or build upon this work, you may distribute the resulting work only under the same or similar license to this one.
You can attribute me by linking back to the flickr photo page or to http://bendalton.noii.net/
If you need a different, or more flexible licence, please send me a quote for your standard picture rates and requirements and I will be happy to consider.
