Получение изображения из байта TCPCLIENT

I send the image to the server, I noticed that it is receiving the image in several packages, I tried to join the buffers, but it is not working, if I put the image in the picturebox without joining the buffers the image is incomplete

My project consists of several clients and a server that is responsible for passing the imgs


Sending Img
<pre lang="vb">
        Dim imgMemoryStream As MemoryStream = New MemoryStream()
        Dim imgByteArray As Byte()
        Imagem.Save(imgMemoryStream, System.Drawing.Imaging.ImageFormat.Jpeg)
        imgByteArray = imgMemoryStream.GetBuffer()
        serverStream.Write(imgByteArray, 0, imgByteArray.Length)
        serverStream.Flush()

Dim networkStream As NetworkStream = clientSocket.GetStream()
networkStream.Read(bytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))

serverStream.Write(bytesFrom, 0, bytesFrom.Length)
serverStream.Flush()

        Dim networkStream As NetworkStream = clientSocket.GetStream()
        networkStream.Read(bytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))
        Dim buffSize As Integer
        Dim inStream(10024) As Byte
        buffSize = clientSocket.ReceiveBufferSize

        serverStream.Read(inStream, 0, buffSize)
        Dim imgMemoryStream = New IO.MemoryStream(img)
        PictureBox1.Image = Drawing.Image.FromStream(imgMemoryStream)



Can anyone give me an example of how to join the bytes that are sent from the server into a single variable?

I put it to the client to send a message containing the length of the image, the other client would receive the length and wait for the bytes, and would join in a var, everything went well except for the piece of joining the bytes
