Imports System.IO

Public Class Form1
    Private PATH As String = Directory.GetCurrentDirectory()
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Dim img1 As Image = Image.FromFile(PATH & "\ExportedBusinessCard0.png")
        Dim img2 As Image = Image.FromFile(PATH & "\ExportedBusinessCard0.png")
        Dim b As Bitmap = MergeImages(img1, img2, 10)
    End Sub
    Private Function MergeImages(ByVal image1 As Image, ByVal image2 As Image, ByVal space As Integer) As Bitmap
        Dim bitmap As New Bitmap(image1.Width + image2.Width + space, Math.Max(image1.Height, image2.Height))
        Using g As Graphics = Graphics.FromImage(bitmap)
            g.Clear(Color.White)
            g.DrawImage(image1, 0, 0)
            g.DrawImage(image2, image1.Width + space, 0)
