If there’s one thing I’ve learnt from writing blog posts, it’s that people barely ever read the whole thing (the majority of people won’t even read this); they read titles. Images are a great way of sparking the interest of the reader to make them read more of your content, as they will see the images and want to know more about them, it also really helps to break up large chunks of writing. There are images relevant to every niche, from screen shots and diagrams to fine art photography.
