I am a user at the danish wikipedia (see Sten Porse), and I'm mostly here to upload my pictures under the categories created by their botanical names.
If you like my images and want to use them in your work, please attribute me with my name and proper license, e.g.: "Sten Porse, license: CC-BY 3.0". I publish my images mostly under CC-BY SA and CC-BY, but some older are under GFDL. If you want a special license, contact me.
