Add Image to a completed product

[Simon Martin]

When completed items are not open for editing, they present a read-only view. However adding an image is not changing the item, so should be allowed.

Need to create a new property in the view model for this and UI elements (probably not the polaroid though)

But details is not a writeable view on the data. Can edit the image as a Stock item (Product)...
