If it is more than downloading for a computer wallpaper or printing and framing it for home, please let me know about it first. Just drop a few lines to firstname.lastname@example.org and describe the planned usage: where, in what size, for what purpose. Then we can discuss the details. The approval is generally quick and simple in case of non-commercial purpose, especially charity issues. For commercial usage (and some personal ones, e.g. huge wall decorations), the licensing options must be discussed. Check the contact page for detailed info.
