Laravel doesn't show the image if it's concatenated with other image

Laravel doesn't show the image if it's concatenated with another image. I'm using Laravel 5.6. Any solution?

<div class="card-img mt-2 mb-2">
  <img src=" " class="position-static  img-fluid rounded" height="300px" width="200px"  alt="">
</div>
