You just save photos to Personal Folder, this is a sandbox folder on iOS. You can use dependency service to write images to system's album.

Firstly create an interface in PCL:

public interface ISavePhotosToAlbum
{
    void SavePhotosWithStream(Stream stream);
}

After downloading the image, use this to write in native:

HttpWebRequest aRequest = (HttpWebRequest)WebRequest.Create(urlStr);
HttpWebResponse aResponse = (HttpWebResponse)aRequest.GetResponse();

DependencyService.Get<ISavePhotosToAlbum>().SavePhotosWithStream(aResponse.GetResponseStream());

At last we should implement this Denpendency Service on native platform:

[assembly: Dependency(typeof(SaveToAlbum))]
namespace SavePhotosDemo.iOS
{
    public class SaveToAlbum : ISavePhotosToAlbum
    {
        public void SavePhotosWithStream(Stream stream)
        {
            var imageData = NSData.FromStream(stream);
            var image = UIImage.LoadFromData(imageData);

            image.SaveToPhotosAlbum((img, error) =>
            {

            });
        }
    }
}

Please notice that: on iOS when you want to write photos to album, we need to add Privacy in info.plist. On iOS 11 add NSPhotoLibraryAddUsageDescription, iOS 10 add NSPhotoLibraryUsageDescription.
