Normally, woocommerce reviews does not allow photo upload. It looks like you are using a third party plugin to add that upload functionality. So mostly people will not have that third party plugin and if I do implement what you are asking for, it will not work for anyone.
Unfortunately I can not add such functionality in my plugin as I have to think of all types of users.
If woocommerce itself adds image upload functionality in their default review then I can add that in my plugin too.
What you are looking for comes under custom development and you need to hire a developer for this. If you want me to do this then I’ll charge you some $. Kindly reply with your best email (make the reply private) and I’ll get back to you with more info.
