Help in this code to upload and delete image on public folder

Hello everyone! How are you?

I'm having a hard time uploading a photo and deleting it.

Sending is okay, but when I delete the image and send a new one the old photo that is returning and not the new one.

What am I doing:

I use the webcam to take the photo and in base64 convert with the base64_decode of laravel.

But deleting I think that just deleting already solves, but it is not!

Functions:

public function saveImagem($img,$id,$path)
{
    //$img = base64_decode($img);
    $img = str_replace('data:image/png;base64,', '', $img);
    $img = str_replace(' ', '+', $img);
    $imgName = $id.'.png';
    $path = public_path().'/uploads/'.$path.'/'.$imgName;
    \File::put($path, base64_decode($img));
    return $imgName;
}

public function destroyImagem($photo, $path)
{
    $imgName = $photo.'.png';
    $fileDir = public_path().'/uploads/'.$path.'/';
    if(\File::exists($fileDir . $imgName)){
        \Storage::delete($fileDir . $imgName);
        return true;
    }
    return false;
}

Can someone help me?

Thanks in advance!
