列跳到Bootstrap中的小设备上的下一行

I am trying to make a simple layout using Bootstrap 3, and it looks fine on laptop, but when I try to emulate in Chrome for small screen such as Iphone 5, one of my image is going to the next row, though I was expecting it to be at the same row as the heading. Visually, there seems to be enough space, and I tried pulling, pushing, applying offser but could not get it working yet.I am trying to make a simple layout using Boots
