Drupal 8.x

I have added a file field to the article content type. I want non-coder admin's to be able to control the position of where the file goes - how do i achieve this in Drupal 8. i.e. some text then a file then some more text?

This may be a newbie question but In the Theming Guide it says:

It is also possible to "theme" only certain sections of a site, certain types of content, or even individual pages.

Hello, help me please with my problem. When I try to install module layout_plugin, installation process stops on 67%. what could be the problem? Sometimes it happens with other modules. Screenshot with a problem ( http://dl3.joxi.net/drive/0013/1491/853459/160326/c264ebf6f9.jpg ). Help me please

Hi,
can anyone help me out to add multiple custom blocks in primary menu in the bartik theme.Thanks in advance :)

How can I change the count number that is produced by the Statistics module to be displayed as a formatted number. So instead of "123456" display "123,456"?

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.
