Can't seem to get it working

I have wordpress installed in a sub directory and have the plugin installed.

My .htaccess looks like this:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /inspiration/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /inspiration/index.php [L]
</IfModule>

# END WordPress

# BEGIN WP-PICShield
# Header always append X-Frame-Options SAMEORIGIN
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} \.(jpg|jpeg|png|gif)$ [NC]
RewriteCond %{REMOTE_ADDR} !^(127.0.0.1|77.72.0.66)$ [NC]
RewriteCond %{REMOTE_ADDR} !^66.6.(32|33|36|44|45|46). [NC]
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?(www.butterflywish.co.uk|translate.google.com|translate.googleusercontent.com|www.microsofttranslator.com|pinterest.com|tumblr.com|facebook.com|plus.google|twitter.com) [NC]
RewriteCond %{HTTP_USER_AGENT} !(googlebot|msnbot|baiduspider|slurp|webcrawler|teoma|photon|facebookexternalhit|pinterest|feedfetcher) [NC]
RewriteCond %{HTTP_USER_AGENT} !(photon|smush.it|akamai|cloudfront|netdna|bitgravity|maxcdn|edgecast|limelight) [NC]
RewriteRule (.*) byrev-wp-picshield.php?key=8h0T-yvUm&src=$1 [L]
</IfModule>
# END WP-PICShield

When I click on images from Google images they go straight to the image with no redirection. Could this be something to do with my .htaccess from the main directory?

Just to add my site is here https://www.butterflywish.co.uk/inspiration/
I would appreciate the help,
Thanks,
Alex.
