Help with where in Laravel

Hi everyone, I wanted your help in a where.

In my system it is like this, I am on the photo gallery page of the Resort (id = 1), on this page I can register the photos of the month / year of the development (the steps of the work). When I register the photos create a button on the same page with a month / year title (Ex: December / 2014) and if you have it in January it will register the photos from January / 2015. And when I click on this button it is to open a modal with the photos referring only to that month / year (December / 2014) of the project (id = 1).

I managed to do this with Ajax passing the values and returning the photos, but now I have a problem, when I click the button (December 2014), it opens the modal and pulls all the photos of the project with the id = 1, let's say I registered (8 photos in December / 2014) and (6 photos January / 2015) it should pull only the 8 photos in December / 2014 and not the 14 photos.

Enterprise screen:

Bank:

Ajax code:

$('.requerAjax').click(function(e) {
e.preventDefault();

var resultado = $(this).attr('rel').split('/');
var mes = resultado[0];
var ano = resultado[1];
var categorias_id = resultado[2];

$.ajax({
    type: "POST",
    url: "/admin/empreendimento/fotos-ajax",
    data: { mes: mes, ano: ano, categorias_id: categorias_id }, 
    datatype: 'json',
    beforeSend: function(){
        $(".carregando").show();
    },
    success: function(result){       
        $(".carregando").hide();
        var html = "";
        for (var i = 0; i < result.length; i++) {                
            html += "<img src=" + result[i].imagem + " alt=''>";            
        }
        $( ".modal-body .gallery" ).html(html); 
    }
});

});

Controller code received from ajax:

public function postFotosAjax() {
    // $mesAno = Input::all();
    $mes = Input::get('mes');
    $ano = Input::get('ano');
    $id = Input::get('categorias_id');

    if(Request::ajax()){
        $FotosMesAno = DB::table('fotos')
        ->select('mes', 'ano', 'imagem')
        ->where('mes', '=', $mes) // Tem que ser um MES.
        ->where('ano', '=', $ano, 'AND') // Tem que ser um ANO.
        ->where('categorias_id', '=', $id, 'AND') // Tem que ser um ID DO EMPREENDIMENTO.
        ->get();
        return Response::json($FotosMesAno);
    }
}

I explore how each screen looks:

Can someone help me, pull the pictures of each month / year?
