Scroll down to Record List section. The area of particular interest to you is the Feed-Style Record List. Inside you'll find the link to a!listViewItem, which is where you put the documentImages you've customized. This should provide you what you need.
You can also use the Grid Layout in the Record List View and choose an appropriate Image to display in a column.
Thank you for the answer , will look into it .
