Watermark not drawing in image

Question

I had an error come up: A Graphics Object cannot be Created from an Image that has an Indexed Pixel Format

So I implemented this code into my method: Solution for "A Graphics Object cannot be Created from an Image that has an Indexed Pixel Format"

But now my watermark doesnt want to draw on my image.

Please can anyone assist.

Code:

private Image AddWaterMark(Image original)
{
    Image waterMark = Image.FromFile(ConfigurationManager.AppSettings["GalleryFolder"] + @"\watermark.png");
    Bitmap bm = (Bitmap)original;

    Size waterMarkResize = ResizeFit(new Size(original.Width, original.Height));

    using (Image watermarkImage = new Bitmap(waterMark, waterMarkResize))
    using (Graphics imageGraphics = Graphics.FromImage(new Bitmap(bm.Width, bm.Height)))
    {
        imageGraphics.DrawImage(bm, new Rectangle(0, 0, bm.Width, bm.Height), 0, 0, bm.Width, bm.Height, GraphicsUnit.Pixel);
        using (TextureBrush watermarkBrush = new TextureBrush(watermarkImage))
        {
            int x = (original.Width / 2 - watermarkImage.Width / 2);
            int y = (original.Height / 2 - watermarkImage.Height / 2);
            watermarkBrush.TranslateTransform(x, y);
            imageGraphics.FillRectangle(watermarkBrush, new Rectangle(new Point(x, y), new Size(watermarkImage.Width + 1, watermarkImage.Height)));
        }
    }

    return bm;
}

You're creating a new Bitmap to pass to Graphics.FromImage then returning the uneditted original Bitmap. Create the new Bitmap independently, pass it to FromImage then return the new Bitmap.

var edit = new Bitmap(bm.Width, bm.Height);
// ...
using (Graphics imagesGraphics = Graphics.FromImage(edit))
{
    // draw original
    // draw watermark
}
return edit;
