It’s the code that you already added. If you want to remove the background image then remove the code that you added to the .slider-wide in your css (same code we talked about in the above posts) –
background: url(http://hardmoney.com/wp-content/uploads/2014/05/New-York-Properties2.jpg);
You won’t need the background image if you’re adding it to your widget area directly/inline, so that’s why I would recommend removing it.
It should be located around line 1187 in your css.
