Try something like...

    Dim id As String = "22137471"
    Dim folder As String = "c:\some path\folder"
    Dim filename As String = System.IO.Path.Combine(folder, id & ".png")
    PictureBox1.Image = Image.FromFile(filename)

You can try this:

PictureBox1.Image = Image.FromFile("c:\some path\folder\myImage.jpg")
