From here you can create new posts and edit your existing posts. Ideally, each post will have at least one image. The image that will be used as the post’s “featured image” for thumbnails is the first image shown within the post. Adding an image at the very top is a good way to start.
Use the “Add Media” button during editing to submit an image, then add it into the post where most relevant. The ideal size for the “featured image” is at least 720 pixels wide, bigger is better. Thanks for your submission!
