Sick of adding a image to your post content then also setting it as the featured image in a separate action? Of course you are!
This plugin solves this problem by adding a new button alongside the “Insert into post” button in the media manager modal. When clicked, this button will insert your selected media and then, if you have selected an image, set that image as the post’s featured image.
It is possible to select multiple media items to insert, so this plugin will set the last image in the selected set as the featured image. The button will appear in the media manager modal for all post types.
This plugin works with WordPress 5.0+, but it will only work with Classic block or in the Classic Editor. It does not currently work with the Image block (or any other similar ones).

Instant Featured Image

Set an image as the featured image at the same time as you insert it into the post content.

Clickable Featured Image for Lightbox & Archives is a WordPress plugin that enhances your featured images by making them clickable, opening the full-size image in a lightbox on single post pages, and linking to the post itself on archive pages like category listings.
