How to Add a Custom Post Status to Quick Edit
I think you can find a lot of good information about status creation in WP. But I didn’t find any notes about how to add a status (custom status, you just created) into inline post edit.

Image Sizes
In this tutorial we are going to talk about image sizes in WordPress. Well, but what image sizes are exactly?
All right, if you open your WordPress /wp-content/uploads
directory, you might find something like this there:

As you can see, an image you’ve uploaded once was duplicated multiple times with different image sizes. And in this case I am just using default WordPress theme with no plugins installed.
Users who don’t know what is the thing – image sizes in WordPress could be terrified by what they see in uploads directory.
The key idea is that when you upload an original image (especially unoptimized, up to 10MB) it would stupid to use this exact file everywhere on the website. Maybe you have a list of recent posts displayed somewhere with 100×100px thumbnails and what about srcset
and sizes
attributes of course?
A great example is the list of products in WooCommerce in admin area:

Needless to say that using image resizing software is also not a great idea because it will create huge performance issues on your server.
That’s why WordPress creates so many image copies and in this tutorial we are going to learn to manage them.
