When writing a KB article or a blog post, choosing a cover image might seem like a skippable step, but in fact it often is an important one. A cover is a must-have on ideally any article, as it provides quite a few benefits:
* With some pagination templates, it gives the reading view a bit of color and graphicality, especially important for the reader (both ourselves and the visitors) when the article body doesn't contain any image.
** This is also valid (and maybe more so) for lists and grids of posts on the website, where it's nice to see each entry have a diverse picture.
* Grabbing the feeble attention of people who might see your post in their news or social media feed, or in a group chat.
* SEO advantages, as the article is more likely to be found for multiple search sources and inputs.
After seeing all the benefits listed above, I think it's easy to spot some natural requirements that the image must possess to be really good for the cause, which by themselves bring other benefits to the mix:
* Easy on the eyes, with low complexity, but colorful and eye-catching at the same time.
* Bringing some kind of attention to the article core, even before the reading starts.
** Ideally, conveying also the same core emotion or feeling the article revolves around.
All of this does feel like a chore when you actually come to do it practice --- and sometimes impossible --- I have to admit that, but there are a few ways to make the work less painful:
* Sometimes, ''editing and styling photos from the article body, or making some other dedicated to the cover in this same fashion'', is more than good.
