I’m not able to save multiple images in my database, follow my code below to in the highlighted line with the arrow (-->).

Observing: when it was just a normal saving image.

public function store(Request $request)
{
    $this->validate($request, [
        'descricao' => 'required',
        'valor' => 'required',
        'id_categorias' => 'required'
    ]);

    //verifica se a img existe e faz a validação da mesma
--> if ($request->hasFile('imagem') && $request->file('imagem')->isValid()) 
    {
        $filePath = $request->file('imagem')->store('public');
        foreach ($request->file('imagem') as $imagem){
        ProdutosImg::create([
           'id_produto' =>$request->id,
            'imagem' => $filePath,
        ]);
        }

        $produto = Produto::create([
            'descricao' => $request['descricao'],
            'valor' => $request['valor'],
            'id_categorias' => $request['id_categorias'],
            'imagem' => $filePath,
        ]);

        \Session::flash('mensagem_sucesso_produtos', 'Produto cadastrado com sucesso!!');
        return Redirect::to('produtos');
    } else {
        Produto::create($request->all());
        \Session::flash('mensagem_sucesso_produtos', 'Produto cadastrado com sucesso!!');
        return Redirect::to('produtos');
    }
}

The solution is that instead of just doing with an image your code has to iterate on the result of several images, in this case it is a array now, example:

if ($request->hasFile('imagem')) 
{
    foreach($request->file('imagem') as $imagem)
    {
        if ($imagem->isValid())
        {
            $filePath = $imagem->store('public');

            ProdutosImg::create([
                'id_produto' => $request->id,
                'imagem' => $filePath,
            ]);

            $produto = Produto::create([
                'descricao' => $request['descricao'],
                'valor' => $request['valor'],
                'id_categorias' => $request['id_categorias'],
                'imagem' => $filePath,
            ]);
        }
    }
}

the code is what you need to solve the problem and to understand that when passing image in a field configured with multiple, the code reproduced by Larable generates a array of information then need to check position to position the data sent to the server, for example the result of $request->file with the command var_dump

array(2) {
  [0]=>
  object(Illuminate\Http\UploadedFile)#207 (8) {
    ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    bool(false)
    ["originalName":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    string(5) "2.png"
    ["mimeType":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    string(9) "image/png"
    ["size":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    int(34686)
    ["error":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    int(0)
    ["hashName":protected]=>
    NULL
    ["pathName":"SplFileInfo":private]=>
    string(27) "C:\Windows\Temp\php81C4.tmp"
    ["fileName":"SplFileInfo":private]=>
    string(11) "php81C4.tmp"
  }
  [1]=>
  object(Illuminate\Http\UploadedFile)#208 (8) {
    ["test":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    bool(false)
    ["originalName":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    string(8) "1600.png"
    ["mimeType":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    string(9) "image/png"
    ["size":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    int(52826)
    ["error":"Symfony\Component\HttpFoundation\File\UploadedFile":private]=>
    int(0)
    ["hashName":protected]=>
    NULL
    ["pathName":"SplFileInfo":private]=>
    string(27) "C:\Windows\Temp\php81C5.tmp"
    ["fileName":"SplFileInfo":private]=>
    string(11) "php81C5.tmp"
  }
}

checking the result was sent two photos, so it is always so when uploaded photos in a field configured with multiple.
