Pictures suddenly duplicating

I have been using Clean Magazine on my site, HuntingtonNow.com for more than 2 years. Suddenly the site is duplicating photos on every post and I cannot get rid of it. The site seems to allow two options for photo display: none or excerpt to the left, which is what I've been using. This happened suddenly and without my having made any theme changes. Can someone tell me how to fix this? It looks horrible. thank you.
