Option to disable pictures and media preview in notifications

### Your use case

#### What would you like to do?

I would like to disable inline pictures showing in the system notifications.

#### Why would you like to do it?

I only want to have a quick glance at the pending messages. Pictures just take too much space in the notification area and force me to scroll more.

#### How would you like to achieve it?

It would be nice to add an option to disable this and only show text in notifications.

### Have you considered any alternatives?

Disabling all notifications, but that's not practical.
