//在2005下编译上边的那句那错了？

Filename(1) = Application.StartupPath & "E:\IMG_0674.JPG "
Filename(2) = Application.StartupPath & "E:\IMG_0675.JPG "
Filename(3) = Application.StartupPath & "E:\IMG_0676.JPG "
Filename(4) = Application.StartupPath & "E:\IMG_0677.JPG "

End Sub
End Class
[解决办法]
Filename(1) = Application.StartupPath & "E:\IMG_0674.JPG "
Application.StartupPath 是您EXE文件的存放路径，您在后面又加上一个绝对路径，这个可能就不对了，所以Image.FileFrom方法就不能取道正确的文件了。
[解决办法]
Application.StartupPath
就是您正在写的这个程序的EXE文件的存放路径。
[解决办法]
如果您的图片是 "E:\IMG_0674.JPG "，那么把Application.StartupPath去掉就好了。
