Problems with Linq(join) - asp.net-mvc-3

Question

I am writting a query with linq(follow code bellow). I am looking for data from db.imovel and for each one bring a picture nested into db.fotoimovel. Keep in mind that I may have more than one picture for each db.imovel data.
The issue is when I run, it returns me all the pictures with the same db.imovel data in all of them.
It works for me if return the db.imovel data with just one(may be the first picture) from db.fotoimovel.
Code:
var retorno = (from c in db.fotoimovel
join p in db.imovel on c.idImovel equals p.idImovel
where p.MetragemImovel >= metragem1 && p.MetragemImovel <= metragem2 &&
p.StatusImovel == opcao &&
((String.IsNullOrEmpty(bairro)) || p.BairroImovel == bairro) &&
((imovel == null) || (p.TipoImovel == imovel)) &&
((carros == null) || (p.QtdVagaGaragemImovel == carros)) &&
((quartos == null) || (p.QtdQuartoImovel == quartos))
select new DadosImovel
{
Id = p.idImovel,
Titulo = p.TituloImovel,
Descricao = p.DescricaoImovel,
Foto = c.NomeFotoImovel,
TipoImovel = p.TipoImovel,
Endereco = p.EnderecoImovel,
Complemento = p.ComplementoImovel,
Bairro = p.BairroImovel,
Cidade = p.CidadeImovel,
Estado = p.EstadoImovel,
CEP = p.CEPImovel,
MetragemImovel = p.MetragemImovel,
QtdComodoImovel = p.QtdComodoImovel,
QtdQuartoImovel = p.QtdQuartoImovel,
QtdBanheiroImovel = p.QtdBanheiroImovel,
QtdVagaGaragemImovel = p.QtdVagaGaragemImovel,
QtdAndarImovel = p.QtdAndarImovel,
Status = p.StatusImovel,
Ativo = p.AtivoImovel
}).Distinct().ToList();
