How to properly organize file saving in Doctrine entities?

Question

symfony

Let's say we have a news entity with standard news fields: title, publication date, text, "picture to draw attention". Here is about the last point and the question.
I read the recommendations from here: symfony.com/doc/current/cookbook/doctrine/file_upl... My hair stood on end for the following reasons:
1. It turns out that "News" knows too much about implementation details. News absolutely no need to know the details about the file system.
2. Write this sausage every time I need to upload files?
But, apparently, the authors meant that their Document entity is intended only for storing a . After some thought, I came up with the following scenarios:
1. Select pictures into a separate entity "Picture" and attach it one-by-one to News.
2. Write your own Image class and store objects of this class inside News in a serialized form.
Actually, the question is: Is there a third way that I don't see? In general, are there any best practices in this regard?
