使用者可自行選擇，把大量的影像做合併，顯示於PictureBox與儲存成影像檔
主要會撰寫這個程式的原因，在於看到藍色小舖上有一個問題一直都沒有人去解，問題是批次圖檔合併，對於此問題我還蠻有興趣的，隨即開始找了一些解決的方法，我的概念大概分成兩個部份
第一部分:將資料夾內要合併的圖檔名稱顯示於Listbox
在此部份，上網找了關於如何快速獲取檔案名稱的範例，很慶幸在章立民老師的網站看到此相關文章，有興趣的同學的可以去看看
Visual C# 2005 - 如何取得某目錄之下所有檔案名稱的字串集合

第二部份:讀取與合併影像
在此部份，是透過 Bitmap 與 PictureBox 來完成
主要的流程如下
1. 把要合併影像，宣告為 Bitmap 陣列
2. 開一張新的畫布來存放要合併的影像，在本程式中，我是將影像橫向的串接合併，因此寬度為所有影像的寬度總和，
高度的話我是找出最高的影像的高度值當作新畫布的高度。
3. 依序將要合併的影像加到新的 Bitmap 物件裡
4. 將合併結果顯示於PictureBox以及儲存成影像檔
