Adding Multple Images to the Clipboard in C#

How would I go about adding multiple images to the clipboard in c#...if it is even possible. I've tried adding an array of images, converting the images to byte arrays combining then converting to an image, and a couple of other methods. I've also searched nuget for a package to manage the clipboard but I could not find one.

Images is a List where the byte array is an png

Here's my code:

private void Copy_Click(object sender1, EventArgs eventArgs){

        //List<Image> test (failed)

        List<Image> images = new List<Image>();
        foreach (int v in lvDocumentImages.SelectedIndices)
            images.Add(ByteToImage(Images[v]));

        Clipboard.SetData(DataFormats.Bitmap, images);

       //Combined byte array test (failed)

       var bytes = new byte[] { };
       foreach(int i in lvDocumentImages.SelectedIndices)
           bytes = Combine(bytes,Images[i];
       Clipboard.SetData(DataFormats.Bitmap, ByteToImage(bytes));


      //Suggested article implementation (Failed)
       Clipboard.Clear();
       List<Image> images = new List<Image>();
       foreach (int v in lvDocumentImages.SelectedIndices)
           images.Add(ByteToImage(Images[v]));

       DataObject newObject = new DataObject(images);
       newObject.SetData(images);
       Clipboard.SetDataObject(newObject);
}

//Merges byte arrays, returns combined
private byte[] Combine(params byte[][] arrays){
        byte[] rv = new byte[arrays.Sum(a => a.Length)];
        int offset = 0;
        foreach (byte[] array in arrays)
        {
            System.Buffer.BlockCopy(array, 0, rv, offset, array.Length);
            offset += array.Length;
        }
        return rv;
    }

//Creates a bitmap from the byte array
private static Bitmap ByteToImage(byte[] blob){
        var mStream = new MemoryStream();
        var pData = blob;
        mStream.Write(pData, 0, Convert.ToInt32(pData.Length));
        var bm = new Bitmap(mStream, false);
        mStream.Dispose();
        return bm;
    }

i face the same requirements , which i do not want to save images to file and add files path to clipboard ,i try this solution and it worked fine:

 RichTextBox temp = new RichTextBox();
                foreach (byte[] data in ArrayOfImagesBytes)
                    {
                    Clipboard.Clear();
                    Bitmap b = new Bitmap(new MemoryStream(data));
                    Clipboard.SetImage(b);
                    temp.Paste();
                    }
                Clipboard.Clear();
                Clipboard.SetText(temp.Rtf, TextDataFormat.Rtf);

Have a look at this answer, its uses the ClipBoard Class to add multiple files to the clipboard, these could be images?
