You can remove the second Person definition because it's already linked to this itemtype via the same itemid:

<div itemtype="https://schema.org/Person" itemscope="" itemid="https://website.com/name/#profile">
    <meta itemprop="name" content="MyName">
</div>
<div itemtype="https://schema.org/ImageObject" itemscope="">
    <link itemprop="url" href="https://website.com/img.jpg">
    <meta itemprop="creator" itemid="https://website.com/name/#profile" itemscope="">
</div>
