[001]在工作表中插入图片
使用Insert方法，例如，下面的代码将从Web网上相应的地址中获取图片并在当前工作表中以活动单元格为起点放置图片。
Sub InsertPicture()
ActiveSheet.Pictures.Insert“UploadFiles/2006-10/1025523341.jpg"
End Sub
同理，下面的代码将从您的计算机中的C盘相应文件夹中获取图片并在当前工作表中以活动单元格为起点放置图片。
Sub InsertPicture()
   ActiveSheet.Pictures.Insert _
     "C:\Documents and Settings\All Users\Documents\MyPictures\示例图片\Water lilies.jpg"
End Sub
[002]将所选单元格区域存储为图片

   OpenClipboard hwnd
    hPtr =GetClipboardData(CF_BITMAP)
    SavePictureCreateBitmapPicture(hPtr), strFileName
   CloseClipboard

Function CreateBitmapPicture(ByVal hBmp As Long) As IPicture
    Dim lngR AsLong, Pic As PicBmp, IPic As IPicture, IID_IDispatch As Guid
    WithIID_IDispatch
     .Data1 = &H20400
     .Data4(0) = &HC0
     .Data4(7) = &H46
    EndWith
    WithPic
     .Size = Len(Pic)
     .Type = 1
     .hBmp = hBmp
    EndWith
    lngR =OleCreatePictureIndirect(Pic, IID_IDispatch, 1, IPic)
    SetCreateBitmapPicture = IPic

  Sub selectRangeToBmp()
    Dim rng AsRange
    Dim strNameAs String
    On ErrorResume Next
    Set rng =Application.InputBox(prompt:="请选择单元格区域",Title:="将单元格区域存储为图片", Type:=8)
    strName =InputBox(prompt:="请输入完整路径和扩展名的文件名",Title:="输入文件名")
    SaveImagerng, strName
  End Sub
[代码说明]运行selectRangeToBmp()程序后，将出现两个对话框，第一个对话框要求用户选择当前工作表中想要存储为图片的单元格区域，第二个对话框要求用户输入图片的存放位置和文件名，要求写出完整的文件路径且须带.bmp或.jpg等扩展名，例如C:\<文件夹和子文件夹>\<文件名>.<扩展名
