Form with two buttons

here:

  def llamada
    if (params[:op].nil?) then
      if (params[:op] == "delImage") then
        destroy #Borra imagen
      elsif (params[:op] == "addImage") then
        addImagenContenido #Añade imagen
      end
    end
  end

maybe you wanted to use unless(params[:op].nil?)
