The result is a picture can not appear in laravel

Is your img src tag working in development server?

If the development server, but when uploaded to the server hosting the picture can not appear

Does everything else work like editing a record adding a record, etc. Check this because the production server if it's Linux is going to be case sensitive. Verify the files are being stored. Check any log files for errors.

The process of uploading the image file can be. But when that data can not be performed.

Look at the 'view source' in the browser and check the path that is being created.

Show what else you have in your view around the echo statement. How is that echo being used?

If its just an image then why not use blade tags;

    <img src="{{ asset('/uploads/event/content/' . $finish_file_name) }}" />

Snapey: Code to upload and display images I wrote in router.php not view

My Code Can not override image:

    Route::post('ajaximage', function(){
        if(empty($_FILES['file']))
        {
            exit(); 
        }
    else
        {
            /*--------------------Start Pengolahan Gambar---------------*/
            $size      = Input::file('file')->getSize(); // ukuran asli file
            $tmp_name=Input::file('file')->getPathName();
            $image = Input::file('file'); // form input gambar
            //$file = Request::file('file');
            $filename  = time() . '.' . $image->getClientOriginalExtension(); // Ektensi file asli -----pakai
            /*----start buat nama file-----*/
            $date=date('ymd');
            $hours=date('His');
            $kyt='KILO';
            $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789_";
            $acakx = "";
            for($i=0; $i<12; $i++)
            $acakx.=$chars[mt_rand(0,strlen($chars)-1)];
            $name_rand1=$date.$hours.$kyt.$acakx;
            $name_rand2 = rand(1000,100000)."-".$filename;
            $file_name=$name_rand1."content".$name_rand2;
            $finish_file_name = strtolower($file_name);
            /*----end buat nama file-----*/
    
            $dir_name = "uploads/event/content/"; // folder tempat upload file
            $path = public_path($dir_name.$finish_file_name); // lokasi penyimpanan gambar 
            $widthx=450; //lebar gambar
            $sizexx=GetimageSize($tmp_name); //Mengambil ukuran gambar yang asli
            $heightx=round($widthx*$sizexx[1]/$sizexx[0]); // rumus konversi mengecilkan gambar
    
            Image::make($image->getRealPath())->resize($widthx, $heightx)->save($path); // Membuat ulang gambar sesuai  
            dengan ukuran baru
        
            echo url().'/uploads/event/content/'.$finish_file_name;
        }
    });
