Displaying Images in a GridView Column

I am referencing this: http://www.c-sharpcorner.com/UploadFile/5089e0/show-image-in-gridview-using-Asp-Net/ 

 

But I want to load an image from a folder and store the entire image and image name in the database. Then to display it in a gridview, I don't want to reference a file folder path. I only want to get the image and name from the database and not reference a file folder path. So how do I do that?
