How to assign images to a category
On the blog page of the Thrive theme, you can add links to up to three featured categories. For best results, you should assign images to the categories that you wish to feature.
To assign an image to a category, hover over Posts in the left-hand menu of WordPress and click on Categories.
Once you are on the Categories page, select the category that you want to assign an image to from the list on the right-hand side of the screen.
At the bottom of this page, you will see that you have the image option. To upload an image, click Add Image. You can then either select an image from the media library or upload a new image.
Once you have selected an image, click Update at the bottom of the page.
You can also assign an image to a new category when you set it up via the Categories page.
