title: What Alt text to use on a list of images (of books)
body: <p>On a page I have a list of books (only the name and the authors), with their coverpage.</p>
  
  <p><strong>What alt-text should I use on those images?</strong></p>
  
  <p>I have seen a large Dutch online webshop which has the name of the product in the product image;</p>
  
  <p>I have seen 'product details' on all items a page on Amazon with lots of products (so they all have the same alt text)</p>
  
  <p>I wonder what would be good to have when someone has a screenreader. Should I just make it blank so it gets ignored? That sounds lazy, but I don't know what good it would be to listen to the screenreader read 30 books and then say at every book either 'this is a cover image' or the title of the book (which it also reads out because it is the start of the book-paragraph, so then it would be read twice)</p>
