I'm trying to help my wife post to Steemit. She has an image which displays properly at the start of her story, but is not displayed as a thumbnail when browsing articles.
What am I missing here? Is the thumbnail created automatically from the first image or is there some code we should include in the post to generate a thumbnail?
I have searched and this question seems to come up a lot, but none of the posts I've found have a clear answer to the question.
Thanks for any feedback on this.
