What is the best way to correct GWT telling me I have mobile usability errors in Image directories

[RobertoGusto]

In GWT, I wish to remove / resolve the following errors

• Mobile Usability > Viewport not configured
• Mobile Usability > Small font size
• Mobile Usability > Touch elements too close

The domain www.sandpiperbeacon.com is responsive, and passes the mobile usability test.

A new issue I noticed, is that GWT is reporting 200+ errors just for image index pages such as http://www.sandpiperbeacon.com/images/special-events/ for example.

Website users cannot access these pages (without editing the URL manually) so I don't consider these usability issues. BUT, I hate to see 200+ errors, especially when Google itself says "Websites with mobile usability issues will be demoted in mobile search results."

I could set the image directories to dissalow in Robots.txt, but I do not want the images to stop appearing in image search, so this seems like a flawed solution.

I cannot be the only person experiencing this, but I have been unable to find any suggestions online.

So far, the only possibly helpful suggestion I have found online has been to add

Options-Indexes to my .htaccess file.Found here: https://productforums.google.com/forum/#!topic/webmasters/Z586mcJ3OCM

Roberto, I guess you should try out this method. I'm sure, it will work.

Do let us know if it works out.
