I just have share this website. Unsplash.com https://unsplash.com/ is where you can get photos to use in your blog for FREE.
You can alter them, use them in any way you want. They WANT you to use them!
I have been getting the photos for my blog there recently. These are High Resolution pictures. Many are just breathtaking.
There is a search bar so you can look for something specific if you want. Like I looked for “photos” to use with today’s post.
So give them a look. They are user friendly. You don’t have to JOIN anything!! It’s all FREE! https://unsplash.com/
