Free Photos!
As thanks to the world for having so much lovely stuff in it, and to the owners and contributors to image banks such as Morguefile, Pixabay, and LostandTaken, which make photos available for free to other artists, I am following their example and posting about 2100 of my best photos for other artists to use as they wish, including use in art works for sale. They include textures, nature closeups (flowers etc.), fractals and other computer-generated designs, and more. As of September 2016, you can see and download all of them on Flickr at https://www.flickr.com/photos/136594255@N06/, and I am starting to put them on Morguefile as well; you can see my profile there at https://morguefile.com/creative/lisaleo. (They may ask you to "sign up," but it's free, and they don't send you ads or anything.) On Flickr they're in 19 albums, by topic as shown below (many pictures are in more than one album); on Morguefile you can find them by keywords.
