Comment (by thommo):

 Hi Peter,
 Yes, you're right, adding a new image and creating a new page now works
 exactly as you say.
 The problem is that the site has been live for a long time. In the
 database, the post_name for the media and page in the posts table were
 identical. Previously, the site displayed the page when going to the url
 (this may be because attachment pages are disabled using the Yoast
 plugin?). We had no issues when updating the page (it allowed the
 post_name to remain as it was and the page displayed as expected).
 However, after applying the latest version of WP, going to the URL gave a
 404. And, when we open the page to edit it in the backend, the permalink
 has been altered to add "-2" to the end of it. If we update it, it changes
 the URL for the page which causes a lot of links to break.
 For us, for the two pages affected on this site, we could delete the old
 media files as they were no longer used and the pages worked again.
 What I don't know is whether Yoast played a part in making the site work
 previously and that, if Yoast had not been there, maybe something
 different would have happened.
