The image does not appear in footer (Laravel 5)

My code of footer view is like this :

...
<div class="col-md-4">
                <a href="{{url('/')}}"><img src="images/dwi.png" alt="Travel Agency Logo" /></a>
            </div>
...

I have a few pages. On the home page, the image appear. But on another page, the image does not appear. Whereas all pages using the same view footer. Why the image only appears on the home page?

Thank you
