Saving multiple pages? [ *Resolved*]

[NeonBurner]

how can i add a page onto a tiff and save the bitmap?

Dim img As System.Drawing.Image
        img = Image.FromFile(imgPath)
        Dim fd As System.Drawing.Imaging.FrameDimension = New System.Drawing.Imaging.FrameDimension(img.FrameDimensionsList(0))
 
        txtPages.Text = (img.GetFrameCount(fd).ToString)
        img.SelectActiveFrame(fd, 0)
        PB.Image = img

i know the amount of pages, so how would i add a frame ?
then just

img.Save("C:\test.tif")
