Copying picture from browser does not upload picture but instead uses url

[tolotrasamuel]

When you copy a picture from a browser (for example this image) using right click > copy image and paste it in the editor, it attaches an URL instead of uploading the image data. This is problematic because your site is now going to refer to another server that is not yours to load the image. The server can be down or require authentication, which does not guarantee the availability of the image.
