vb制作的屏保系统，由多张图片循环播放，如何在图片播放时加上一定的特效，比如百叶窗等等，就像PPT制作的一样，请高手帮忙提供代码，将十分感谢，循环播放部分代码如下：
Private Sub Timer1_Timer()
Dim fPath As String, sName As String, N As Integer
fPath = "\\pcmes\FQCshuju\J5机种屏保系统\tupian\"
sName = Dir(fPath & "*.JPG")
Do Until sName = ""
N = N + 1
sName = Dir()
Loop
M = Str(N) + 1
counter = counter + 1
If counter = M Then
counter = 1
End If
No = Trim(Str(counter))
photo.Picture = LoadPicture("\\pcmes\FQCshuju\J5机种屏保系统\tupian\" + No + ".jpg")
End Sub

'这个拿去试一试,两个时钟,两个图片框,自己设定图片框2的大小,比如让它和窗体一样大
'查一查PaintPicture的用法,就明白了
'去掉Picture2
