Dealing with images and databases is basically done with byte arrays.

Here's a one starting point with VB.NET code samples from my blog:
Convert image to byte array and vice versa
Save binary data to SQL Server with VB.NET

You may also try Daniweb's site search. I've answered the same or at least very similar question few times. A pretty good search phrase is "image SQL Server VB.NET" (without quotes).

15. Dim connection As New SqlConnection("connection string here")
16. Dim command As New SqlCommand("UPDATE MyTable SET Picture = @Picture WHERE ID = 1", connection)
17.
18. Using picture As Image = Image.FromFile("file path here")
19. Using stream As New IO.MemoryStream
20. picture.Save(stream, Imaging.ImageFormat.Jpeg)
21. command.Parameters.Add("@Picture", SqlDbType.VarBinary).Value = stream.GetBuffer()
22. End Using
23. End Using
24.
25. connection.Open()
26. command.ExecuteNonQuery()
27. connection.Close()

That works. If you have an existing row to update. If you want to insert a new one, the code changes a bit:
VB.NET Syntax (Toggle Plain Text) 
  1. 16. Dim command As New SqlCommand("INSERT INTO MyTable (Picture) VALUES (@Picture); SELECT @@IDENTITY AS 'Identity'", connection)
  2. 17. Dim ThisPictureID As Integer
  3. 26. ThisPictureID = CInt(command.ExecuteScalar())
Now ThisPictureID contains new ID.
