Adding a Featured Image
Every post and page in WordPress can have its own featured image. Usually, website owners use featured images to make the page more visually appealing to the website's visitors. In most themes, the featured image option is already enabled and it is located in the Featured Image pane on the "Edit Post" and "Edit Page" screens.
- Go to your post or page in WordPress Dashboard, and scroll down to see if there is a pane called Featured Image on the right hand side of the screen.
- In Featured Image pane, click on the Set featured image link and choose or upload your image.
- Once the image is selected, click on Set featured image on the bottom right corner.
- Update or publish your page when you are ready.
