How can I return image from controller asp.net

[AcceptVerbs(HttpVerbs.Get)]
[OutputCache(CacheProfile = "CustomerImages")]
public FileResult Show(int customerId, string imageName)
{
    var path = string.Concat(ConfigData.ImagesDirectory, customerId, "", imageName);
    return new FileStreamResult(new FileStream(path, FileMode.Open), "image/jpeg");
}
