Thumbs up to the Steemit team on the Cover image upgrade. Once I realize the feature was available I wasted no time, check out my cover
What are you waiting on, its quick and simple, all you have to do, go to the setting tab, on the right hand side of the page, under PROFILE PICTURE URL, you would find COVER IMAGE URL. All that's left, finding a cover that you love and its just a pasting the image URL into the box. If you are still confuse just follow the images below
Now you have no excuse, I know we have some serious creative people here, excited to see what you folks would put as your cover image...
