How to convert a HttpPostedfile into a Byte()

Question

For Each postedFile As HttpPostedFile In PictureUpload2.PostedFiles

i am trying to get the postedfile and convert to byte() like:

 Using s As Stream = PostedFile.InputStream


        Using br As New BinaryReader(s)
        Dim image As Byte() = br.ReadBytes(CType(s.Length, Int32))

without success. Only when i execute the following will it obtain the Byte Array ? 
   Dim image As Byte() = PictureUpload2.FileBytes

I am trying to recreate a thumbnail image of all the PostedFiles !
