Images don't show

OK, I’ve read a ton of posts and still cannot figure out how to get images to SHOW in a sub domain blog. They show in the main blog fine. If you have a subdomain blog, they upload fine and never show in the post. A broken image appears. The actual file is in the files/subdirectory for the site. Yes the AllowOverride File Info stuff is set in the conf file. I looked at so many htaccess files, I no longer have a clue as to what is correct and what isn’t. So, here is mine:

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . – [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Main site is https://www.weeklyexpressnews.com sample subdomain site is https://www.bremondhouse.com. The image that is in the about section is hard-coded to the main domain images directory in order for it to work (first one). Second one at the end of the about section has been uploaded and inserted within the page post. It doesn’t show. The link to it brings up a ‘No input file specified’ error in Firefox.
