How to Create a Custom Thumbnail for Your WordPress Post

To make your blog more appealing to look at, use the post’s featured image as a thumbnail beside your latest post. Sometimes, WordPress’s default thumbnail sizes don’t fit the bill so this procedure will also help create sizes to any size you want.
