If I am just using a decorative image, does the Web CMS automatically set the alt attribute to alt In other words, I don't have to do anything in the Description field in the Media Library?
This is correct.
However if your image is clearly a descriptive one, you will need to add a meaningful description to it in the Media Library, which will enable the end user to understanding its content and context.
