This was meant to refer to *the form*, and I think there should be only one 
form for the same purpose for the reason that I mentioned.

However if it works for the form *controls* of an “Image” component for you, 
so much the better.

But what if the user deletes the first instance?

I meant that you *could* forget that it is a form if it is *not* directly 
interactive.  Then you would keep elsewhere the data to be submitted.
