I need to retrieve a users profile image but it somehow doesn´t work the way I intended. Could you advise a good way to get a users profile image?

Here is my code:

            var user = GetLoggedInUser(); // Gets a valid DNN User
            var imageID = new Guid();

            if (user.UserID == -1)
                return imageID;
           
            var uProfileController = new UserProfileController();
            var uProfile = uProfileController.GetUserProfile(user.PortalID, user.UserID);

            var myProfileController = new MyProfileController();
            var myProfile = myProfileController.GetMyProfileByUserProfileId(uProfile.UserProfileId);

            imageID = myProfile.ProfileImageId;

Although the user has a profile it will throw a null reference. Is there a safe way to build the UserProfileImageURL?

Thanks!
