It's a regular feature around here - the free weekly background image. I make them to use in powerpoint slides - but they could be used in any presentation software you like. Or not. Use them at home, work, school, or church. Use them as wall paper for your computer or smart phone. Print them out and use them as actual wall paper. Print them out and make paper airplanes. Use them how you will. I only ask that you share them freely and that you tell others that you found them here.
I'm not sure what kind of purple flowers these are. I saw them at the Olbrich Botanical Gardens in Madison, WI.
