在自定义工具箱中选择dirlistbox，drivelistbox，filelistbox，添加这3个控件，然后在窗体上添加这些控件和一个picturebox控件，代码如下：
Public Class Form1
Private Sub DirListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DirListBox1.SelectedIndexChanged
FileListBox1.Path = DirListBox1.Path
End Sub
Private Sub DriveListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DriveListBox1.SelectedIndexChanged
DirListBox1.Path = DriveListBox1.Drive
End Sub
Private Sub FileListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles FileListBox1.SelectedIndexChanged
PictureBox1.Image = Image.FromFile(FileListBox1.Path + "\" + FileListBox1.SelectedItem.ToString())
End Sub
End Class
你可以自己在修改下，这只是个模型，呵呵！
'没办法，需的把窗口隐藏一下，还的隐藏后延迟一下再截图。
Dim WithEvents Timer1 As New Timer With {.Interval = 30, .Enabled = False}
Dim Imgrect As Rectangle
Dim img As Bitmap
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Imgrect = Me.RectangleToScreen(Me.ClientRectangle)
img = New Bitmap(Imgrect.Width, Imgrect.Height)

窗体上放一个PictureBox，两个CommandButton，一个FileListBox
Private Sub Command1_Click()
If File1.ListIndex = 0 Then
ShowPic File1.ListCount - 1
Else
ShowPic File1.ListIndex - 1
End If
End Sub
Private Sub Command2_Click()
If File1.ListIndex = File1.ListCount - 1 Then
ShowPic 0
Else
ShowPic File1.ListIndex + 1
End If
End Sub
Private Sub Form_Load()
File1.Visible = False
File1.Pattern = "*.jpg;*.gif" '可以浏览的文件类型，使用分号隔开
File1.Path = App.Path '改成你需要浏览的目录，比如"C:\Pic"
If File1.ListCount 1 Then '目录中图片在两张以上可以浏览
ShowPic 0
Exit Sub
ElseIf File1.ListCount = 1 Then '目录中只有一张图片时只显示这一张
ShowPic 0
End If
Command1.Enabled = False
Command2.Enabled = False
End Sub
Private Sub ShowPic(Index As Long)
File1.ListIndex = Index
Picture1.Picture = LoadPicture(File1.Path "\" File1.List(Index))
End Sub

我说选把打开多个图片路径加载到一个listbox里，利用listbox写代码
Private Sub picbox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
If ListBox1.SelectedIndex = count Then
Try
ListBox1.SelectedIndex = ListBox1.SelectedIndex + 1
Catch
ListBox1.SelectedIndex = 0
End Try
End If
picbox.Image = ListBox1.SelectedItem.ToString
End Sub
