一键插入和压缩图片的宏

Question

这是我在Extendoffice上找到的宏

Sub InsertPictures()
'Update 20140513
Dim PicList() As Variant
Dim PicFormat As String
Dim Rng As Range
Dim sShape As Shape
On Error Resume Next
PicList = Application.GetOpenFilename(PicFormat, MultiSelect:=True)
xColIndex = Application.ActiveCell.Column
If IsArray(PicList) Then
    xRowIndex = Application.ActiveCell.Row
    For lLoop = LBound(PicList) To UBound(PicList)
        Set Rng = Cells(xRowIndex, xColIndex)
        Set sShape = ActiveSheet.Shapes.AddPicture(PicList(lLoop), msoFalse, msoCTrue, Rng.Left, Rng.Top, Rng.Width, Rng.Height)
        xRowIndex = xRowIndex + 1
    Next
End If
End Sub

我计划添加一些内容，一旦单击该内容，将插入图像并压缩图像以立即减小文件大小。我需要编写宏的帮助。任何帮助将不胜感激。
