I have a Drupal 8 site up and running and everything seems fine until I create a view to display summaries of news items. I use the first image in a group of images to go with the headline and a summary in the view and it works fine until some hours later when the image goes missing and all I get is the alternative text. I have googled this and it seems that someone had a similar issue in 2006 where the images were stored as temporary. Can anyone say if that is what is happening here and do they know of a fix?

I would appreciate any help here.
Thanks,
John Eardley.
