The Editorial Full Width Article page is used for articles, pages with mostly text, and runs nearly the full width of the page. Currently the most used template for article pages if no side widgets are required.

You can insert images into your text using the Insert Sitecore Media button in the ribbon above.The image is automatically scaled to full width of the page.

Amstel canal Edwin van Eis

This particlar image needs a credit as well. You can add the credit in the HTML of the image so it shows when you hover over the image. Add "title="Image: Peter Elenbaas" to the  tag, like so: ‹img alt="" title="Image: Peter Elenbaas" width="100%" src="/media/canals-and-cityscapes/amstel-en-gebouwen-omval-peter-elenbaas.jpg?la=en" /›

If the image in the Media Library had included an alt text, it would automatically populate in the HTML code. Here, you can see in the  tag that the "alt" field has not been entered in the Media Library. You can add it here in the HTML, or when you insert the image into your article. This is always recommended for SEO purposes. Note, adding the alt text in the HTML does not add the alt text to the image in the Media Library. 

Widgets on this page 

The placeholder below the text provides a space for a number of widgets but we don't generally use these here.

The placeholder at the very bottom below the social buttons by default is the Related cards widget. The default widget gets populated based on the tags on the page.You can also manually set the cards in the Related cards widget.
