This program starts by calculating the name of the file to open. It assumes it is running from the bin directory inside the main project directory that holds the target image file. It uses LastIndexOf to find "\bin" in the executable's directory, uses Substring to remove the end of the path, and adds on the file's name.

Next the program creates a new Bitmap object, passing its constructor the file's name. That loads the file into the Bitmap object. The program sets a PictureBox's Image property to the Bitmap to display the result. It also sets the control's SizeMode property to AutoSize so the whole image is visible.

Private Sub btnLoadPicture_Click(ByVal sender As _
    System.Object, ByVal e As System.EventArgs) Handles _
    btnLoadPicture.Click
    ' Compose the picture's file name.
    Dim file_name As String = Application.ExecutablePath
    file_name = file_name.Substring(0, _
        file_name.LastIndexOf("\bin")) & _
        "\VBHelper2.jpg"

    ' Load the picture into a Bitmap.
    Dim bm As New Bitmap(file_name)

    ' Display the results.
    picImage.Image = bm
    picImage.SizeMode = PictureBoxSizeMode.AutoSize
End Sub
