Answer 1

You can use File facade to delete a file:
use Illuminate\Support\Facades\File;
$pathToFile = base_path('public/img/'.$user->image);
File::delete($pathToFile);

Answer 2

You should first find the user and determine if he already has an image, sou you can delete it from the storage. Do it like this:
public function postEdit (Request $request) {
request()->validate([
'email' => 'required',
'fullname' => 'required',
'birthday' => 'required',
'address' => 'required|min:10',
]);
$user = User::where('id', $request->id)->first();
if($user->image){ //Check if user has image and delete it from storage
if (Storage::exists($user->image)) {
Storage::delete( $user->image ); //Dont forget to use your real paths. $user->image should be a path to an image.
}
}
$image = $request->image;
$id = $request->id;
$email = $request->email;
$fullname = $request->fullname;
$address = $request->address;
$birthday = $request->birthday;
$country = $request->country;
//Insert new image
$image = $request -> file('image');
$destination = base_path().'/public/img';
$file_name = rand(100,1).date('h-i-s');
$image->move($destination, $file_name.".".$image->getClientOriginalExtension());
$img = $file_name.".".$image->getClientOriginalExtension();
//Now update user
$user->update([
'image' => $img,
'email' => $email,
'fullname' => $fullname,
'birthday' => $birthday,
'address' => $address,
'country' => $country,
]);
return Redirect::to("dashboard")->withSuccess('Great! You have Successfully edited');
}
