Not saving a new bitmap c#

I am wanting to show the new bitmap image thats been created. Not save it.

Im using bitmap with graphics in C# and im hoping to return the new image without having to save a new image.

C#

private void GenerateBanner( string titleText ) {

    Bitmap bannerSource = new Bitmap( DefaultBannerPath );
    //bannerSource.Save( PhysicalBannerPath );
    RectangleF rectf = new RectangleF( 430, 50, 650, 50 );

    using (Graphics g = Graphics.FromImage(bannerSource))
    {
        g.SmoothingMode = SmoothingMode.AntiAlias;
        g.InterpolationMode = InterpolationMode.HighQualityBicubic;
        g.PixelOffsetMode = PixelOffsetMode.HighQuality;
        g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit;
        g.DrawString(titleText, new Font("Bradley Hand ITC", 100, FontStyle.Bold), Brushes.White, rectf);
        //bannerSource.Save( PhysicalBannerPath );
    }
}

To return this image from an ASPX page (can be used as img src in HTML), you'll need to use a MemoryStream and convert it to byte[]; then use the Response.BinaryWrite method:

        byte[] bytes;
        using (var stream = new System.IO.MemoryStream())
        {
            bannerSource.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
            bytes = stream.ToArray();
        }

        Response.ContentType = "image/jpeg";
        Response.Clear();
        Response.BinaryWrite(bytes);
        Response.End();
