如何用VBA在WORD里插入指定的图片和指定的尺寸

Sub 插入图片()
Dim filenames As String
 Dim filefilter1 As String
 filefilter1 = ("所有图片文件（*.jpg;*.bmp;*.png;*.gif）,*.jpg;*.bmp;*.png;*.gif")    '所有图片文件后面的括号为中文括号
filenames = Application.GetOpenFilename(filefilter1, , "请选择一个图片文件", , MultiSelect:=False)
 '没有选中文件时，做容错处理
If filenames = "False" Then
 Exit Sub
 End If
 '插入图片到指定的单元格
Sheet1.Pictures.Insert(filenames).Select
 '图片自适应单元格大小
On Error Resume Next
 Dim picW As Single, picH As Single
 Dim cellW As Single, cellH As Single
 Dim rtoW As Single, rtoH As Single
 cellW = ActiveCell.Width
 cellH = ActiveCell.Height
 picW = Selection.ShapeRange.Width
 picH = Selection.ShapeRange.Height
 rtoW = cellW / picW * 0.95
 rtoH = cellH / picH * 0.95
 If rtoW < rtoH Then
     Selection.ShapeRange.ScaleWidth rtoW, msoFalse, msoScaleFromTopLeft
 Else
     Selection.ShapeRange.ScaleHeight rtoH, msoFalse, msoScaleFromTopLeft
 End If
 picW = Selection.ShapeRange.Width
 picH = Selection.ShapeRange.Height
 Selection.ShapeRange.IncrementLeft (cellW - picW) / 2
 Selection.ShapeRange.IncrementTop (cellH - picH) / 2
 End Sub
