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.

Use this plugin to display the featured image for any post or page in your sidebar. If a featured image has been set. If no featured image has been set, the plugin tries to use the image of the parent post/page. Otherwise, no widget is displayed.

Featured Image Widget

This doesn't pull in any photos in the sidebar. The title shows up, but no images are shown. Bummers. Maybe this worked before, but it certainly doesn't now. I am using Twenty Fourteen for the theme.
