Create a nature-themed wallpaper using a wallpaper creation website such as Canva.com or YourOwnWallpaper.com by uploading a photo or choosing from the available selections, adding customizations and saving the file. Alternately, use a graphic design program such as Adobe Photoshop or GIMP to modify the image, add other features, and save it with the appropriate resolution.
Check the resolution of your computer monitor to find the specific dimensions you need for your nature wallpaper. If the image is too small, it may result in a blurry or pixelated final image. Use these dimensions to select a nature image that is the appropriate size, and save it to your computer. If you are using Canva.com or YourOwnWallpaper.com, you may also select from the stock images present on each site, rather than uploading your own image. Each site contains tools for adding additional graphical elements, modifying the image colors and adding custom text, then saving the image for use on your computer.
To create a nature wallpaper with graphic design software, open a new document, and set the length and width to that of your monitor resolution. Alternately, open the nature image with the program, and change the canvas size to the monitor resolution dimensions. Use the drawing, text and shape tools to add additional elements, and use the image modification commands to adjust color and levels. Save the project as an image file for use as a wallpaper.
