Why make a hash out of the name of the pictures?

Question

Images

For example

labels_layer.draw();
          };
          image_obj.src = '/static/catalogue/images/555/saab/5c/95c.cd7572ba4d86.png';
        }

here

<div id="node_image_div" class="col-12 col-lg-6">
          <img class="img-responsive" src="/static/catalogue/images/555/saab/5c/95c.cd7572ba4d86.png" width="555" height="678" />
        </div>

Why is this needed?

Answer 1

What if several images have the same name?
