    It is safe to assume that by fitting you mean covering all of the width. This is because

    1. You typically do not know the height just by using col-sm-6 or col-md-6 or col-lg-4.
    2. There is a huge probability of loss in aspect ratio of the image if you try to resize it according to your own will.

    Use <img src = "images/dummy_image.png" class = "img-responsive" width = "100%" /> for fitting the column. This will fit your image width-wise into the column and will automatically modify the height (keeping the aspect ratio in mind), so you do not have to worry about image getting illogically resized.

    Just add you images width to 100%.

    But as you are saying user will upload various kind of images, so can use object-fit property.

    Add the CSS like this:

    .fit-image{
    width: 100%;
    object-fit: cover;
    height: 300px; /* only if you want fixed height */
    }
    
    <div class="col-sm-6 col-md-6 col-lg-4">
    <img src="images/dummy_image.png" class="img-responsive fit-image">
    </div>

    For Bootstrap 4

    <div class="col-sm-6 col-md-6 col-lg-4">
        <img src="images/dummy_image.png" class="img-fluid">
    </div>
    

    bootstrap.css

    .img-fluid {
      max-width: 100%;
      height: auto
    }
