Load Current Image to Update in Edit Form (Using Form Binding in Laravel 5.5)

I am trying to load the user current image(Image URL saved in db)in Edit Form... If new image in edit form is not selected i get this error...

Undefined variable: image_path

Here is my update function

 public function update(Request $request,User $user)
    {
        $get_user = Auth::user();
        if(Input::hasFile('image'))
        {
            $user_email = $get_user->email;
            $image = request()->file('image');
            $image_extension = $image->guessClientExtension();
            $image_path = $image->storePubliclyAs('public/uploads/profile_images/images', $user_email . ".{$image_extension}");

        }

        $user->firstname = $request->get('firstname');
        $user->lastname = $request->get('lastname');
        $user->company= $request->get('company');
        $user->address= $request->get('address');
        $user->phone = $request->get('phone');
        $user->country=  $request->get('country');
        $user->zipcode = $request->get('zipcode');
        $user->city = $request->get('city');
        $user->state = $request->get('state');
        $user->skills = $request->get('skills');
        $user->interests = $request->get('interests');
        $user->about = $request->get('about');
        $user->website = $request->get('website');
        $user->image_url = $image_path;
        $user->save();

        $request->session()->flash('message.level', 'success');
        $request->session()->flash('message.content', 'Profile Updated Successfully !');
        return redirect()->route('dashboard');

    }
