RE: How to Create an Attractive Post Thumbnail for Your Steemit Blog Posts!
That is mentioned in the post. It may have gotten skipped.
If you have seen my posts previously, most of them have specially designed thumbnails as the first image. The reason for them being the first image is that the first image that you include in your post acts as the default post thumbnail.
Separate upload is not needed. Just add as first image.
