 * I thought that when you upload an image, WP creates several image sizes from 
   the upload. I also thought that WP ensures that the file size of an image is 
   not large. However, in my Media Library, I have many images that are over 1 MB
   in size. How can this be? Thanks.

 * WordPress doesn’t compress or limit the file/image size. To optimize images you’ll
   have to use plugins.

 * Thanks. When you upload an image, how many thumbnails are created?

 * [@engine44](https://wordpress.org/support/users/engine44/) 4 Image size is generated
   by WordPress by default and the full-size image is included in that 4 image size.
   
   3rd party plugins register their own image size if they need it. So a number 
   of image sizes/thumbnails is not fixed.
