Symfony's file form types are not propagated with data from backend. If you would like to show existing file, you have to add it manually in your Twig file.
As you didn't attached your entity code, please note that my example should be used with proper methods from your MyProject\ProductBundle\Entity\Photo class.
In my example you have to pass to the view Photo entity as photo, but only if there was already uploaded file before.
<div class="row_form">
{% if photo is defined %}
Current photo: <img src="{{ photo.getWebPath() }}" />
{% endif %}
{{ form_label(form.Photo, "Photo") }}
{# Génération de l'input. #}
{{ form_widget(form.Photo) }}
</div>
