I have the following two methods that handles taking photos from a camera and picking photos from a library. They\'re both similar methods as at the end of each method, I ge

As Jason said that you can save image path into sqlite database, but if you still want to save byte[] into sqlite database, you need to convert stream into byte[] firstly:

 private byte[] GetImageBytes(Stream stream)
    {
        byte[] ImageBytes;
        using (var memoryStream = new System.IO.MemoryStream())
        {              
            stream.CopyTo(memoryStream);             
            ImageBytes = memoryStream.ToArray();
        }
        return ImageBytes;
    }

Then load byte[] from sqlite, converting into stream.

 public Stream BytesToStream(byte[] bytes)
    {
        Stream stream = new MemoryStream(bytes);
        return stream;
    }

For simple sample, you can take a look: Insert byte[] in sqlite:

 private void insertdata()
    {
        var path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "sqlite1.db3");
        using (var con = new SQLiteConnection(path))
        {
            Image image = new Image();
            image.Content = ConvertStreamtoByte();
            var result = con.Insert(image);

            sl.Children.Add(new Label() { Text = result > 0 ? "insert successful insert" : "fail insert" });
        }
    }

Loading image from sqlite:

 private void getdata()
    {
        var path = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "sqlite1.db3");
        using (var con = new SQLiteConnection(path))
        {
            var image= con.Query<Image>("SELECT content FROM Image ;").FirstOrDefault();

            if(image!=null)
            {
                byte[] b = image.Content;
                Stream ms = new MemoryStream(b);
                image1.Source = ImageSource.FromStream(() => ms);                   
            }

        }
    }

Model:

public class Image
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    public string FileName { get; set; }   
    public byte[] Content { get; set; }
}
