Custom images for blog posts sharing on social media are a must (one generic image is NOT enough)

This is really such a basic feature that I can hardly believe that it's missing here - for sharing blog posts on social media, it's vital that a different image is displayed with different blog posts. And it shouldn't be just a thumbnail, but a full-size image that can be easily noticed in the social media feeds. This significantly increases click-through rate and is thus extremely important for bloggers and writers whose blog success depends on a good response to their social media shares. Without the images, the chances for this are severely diminished, so please, put this feature at the top of your priority list.
