Well the logo might not be a great example, as it is often clickable to the home page and should have alt text so people know what it is.
A better example is when a site has little stock photo thumbnails with article titles on a navigational page. The screen reader can read the title text; knowing what’s in the thumbnail adds nothing.
Images should only have alt text when they contain “real” content (for example if it is an original photo that is relevant to the associated story).
