Inserting images from clipboard/downloading from a computer

[doroved]

I propose to add inserting images from clipboard/uploading from computer to make it faster and more comfortable to create a template, because it takes much longer to prepare an image from a link. And when copying HTML code, images should be replaced with links, e.g. https://cdn.img.com/cat.png, where cat is the name that can be requested when inserting an image.
