I saved this image from Wikimedia and then uploaded it. This file, and most if not all others on Wikimedia, are licenced under the GNU Free Documentation License. The author is Melburnian, and the image is dated January 2007. It was taken at Maranoa Gardens, Balwyn, Victoria, and it's a photo of Grevillea longistyla. Wikimedia has some wonderful images.
It took me a while to work out how to upload - you have to click on the 'add image' icon on the toolbar while you are creating your post. Then you have the option to upload or insert a URL. I found the URL option didn't work, but I could save the image and then upload it.
