unwanted Images show on home page published site but not in editor so I cannot delete them

www.helpthecats444.com (URL not posting yet unless use cloud.com)   Problem:  In editor on the Home page I do not see any unwanted gallery images so I cannot delete them.  When I publish, on the home page upper left are two unwanted images that if I click on them it shows a gallery of pictures.  I need that gallery deleted so it doesn't show on my home page.  Thank you.
