Here are some images that can be used as banners on your WordPress (or other) websites. They are free to use. They originated from a site called Unsplash, which says, “All photos published on Unsplash can be used for free.” Feel free to explore the Unsplash website for more photos, and whenever possible give credit to the photographer.
To use the banners in your own website, click on one of the images to see a large version. Then “right-click” on the image and choose “Save image as…” from the menu. You can now upload that image to your site and add it to a page or post, or in a header for your entire site. If you have any questions on how to do any of this, contact us in CIRT.
