Let's take this blog as an example: Tory Senator Tells Truckers To 'Roll Over Every Liberal Left In The Country'
That image has the caption and this alt info:
<img class="image__src" src="https://o.aolcdn.com/images/dims3/GLOB/crop/751x376+39+39/resize/630x315!/format/jpg/quality/85/https://media-mbst-pub-ue1.s3.amazonaws.com/creatr-uploaded-images/2019-02/01e085f0-3578-11e9-bb2e-b904fadba715" alt="Sen. David Tkachuk was invited to address a crowd of protestors on Parliament Hill on Feb. 19, 2019.">
So what about the title and description? When i look at an image from Moz like this Moz Blog - SEO and Inbound Marketing Blog - Moz
there isn't any info at all so I am wondering if filling out all those fields might be a waste of time?
