 try{

      $file=$request->file('image');
      $filename=$file->getClientOriginalName();
      $imgname = uniqid().$filename;

      $input['image']= $imgname;

    return back()->with('success', 'Article created successfully.');   
    }
catch(ModelNotFoundException $exception){
   // do task when error
    return back()->withError($exception->getMessage())->withInput();    }

 <td><img src=""
                                            width="500px"></td>
