Doubt, I can not send the image.

Path: _img / _products / foto2-verde.png

<input type="radio" name="cor" id="verde" value="verde"> 

<img src="_img/_produtos/foto<?=$_POST['???']?>-<?=$_POST['cor']?>.png">

This last code has to be this: _img / _products / foto2-verde.png

The way it is, it works for me: _img / _products / photo ??? -verde.png

So you're just saying that your id passed by post is undefined (does not exist), but this is normal because you're just passing 'color'

If you want to upload an image you will have to use an 'input' of type 'file' and then in php you will have to use $ _FILE ['TupleNameInputFile'], not to mention that you will have to use the attribute enctype with multipart / form-data value in your form

I solved the problem, the solution is below:

Just add an input type hidden

<input type="hidden" name="numproduto" value="2">

And complement the display code:

<img src="_img/_produtos/foto<?=$_POST['numproduto']?>-<?=$_POST['cor']?>.png"
            class="img-thumbnail img-responsive">
