Larevel Response::download() function image issue

I'm using Laravel 5. I am creating a photo gallery of sorts. When you click on an image I use

Response::download($path,$filename,$headers);

To initiate a download of the file.

Below is my code:

Route

Route::get('test/{filename}', 'ImageController@getDownload');

When the user goes to test/example.png, it runs the getDownload function

Controller

public function getDownload($filename){
    // Define the path and the extension
    $file = public_path() . "/uploads/" . $filename;
    $ext = pathinfo($filename, PATHINFO_EXTENSION);

    if($ext == 'png' || 'PNG'){
      $headers = array(
          'Content-Type:image/png',
        );
    }

    else if($ext == 'jpg' || 'jpeg' || 'JPEG' || 'JPG'){
      $headers = array(
          'Content-Type:image/jpeg',
        );
      }

      else if($ext == 'gif' || 'GIF'){
      $headers = array(
          'Content-Type:image/gif',
        );
      }

      $response = Response::download($file, $filename, $headers);

      return $response;

}

In this function I declare the path to my files and set up the download.

View

@foreach ($fileList as $uploadedFiles)
    <div class='img'>
    <a href="test/{{$uploadedFiles}}"/><img src="{{ $uploadsFolder}}/{{   $uploadedFiles }}"/></a>
    </div>  

@endforeach

In my view I use a loop to get the filenames, then create a link that goes to test/$filename which invokes the method in the Controller.

The problem

Using this approach seems to work as I can download docx files, PDFs, txt files, csv files and more. However, when an image is downloaded, when I open it I get "The image cannot be displayed".

In my uploads folder I have an image named cake.JPG.

When I download this the Request headers are as follows:

• Accept-Encoding: gzip, deflate

With images in particular have I set up the headers incorrectly?

Thank you in advance.
