Excel VBA，VBA程序代码改变图片内容
领导签字图片随机生成。核心的代码不会写，这是一个VBA程序问题。
假如现在有两幅不同图片，图片1，图片2，要求用VBA代码改变图片1的内容为图片
看清问题了噢，只求一行VBA程序代码，其他说再多是没用的~
可能我没有描述清楚噢，图片1，图片2是已经存在Excel的页面中的，而不是文件夹下的。
1.ALT+F11打开VBE编辑器，新建一个模块1，输入如下代码：
Sub picxz() '以插入图片文件原名称作为图形名称，单元格大小为基准，依次先行方向再列方向插入，即先A1,A2....再B1,B2....依次类推
Dim picname As Variant, p As Shape, pname As String, stly, p1 As Shape, pnamewr As String, x As Byte, x1 As Byte, itop, ileft, iheight, iwidth, l As Long, h As Long
Const hs As Long = 65536 '每列所能插入图片的最大个数
stly = vbQuestion & vbYesNo
l = -Int(-Sheets("图库").Shapes.Count / hs) '列号
h = Sheets("图库").Shapes.Count - (l - 1) * hs '行号
picname = Application.GetOpenFilename(FileFilter:="图片文件 (*.jpg; *.gif;*.bmp),*.jpg; *.gif;*.bmp,所有文件(*.*),*.*", _
Title:="图片选择", MultiSelect:=False)
If picname <> False Then
pname = Split(Dir(picname), ".", 2)(0) '取图片文件原名称
pnamewr = pname
itop = Sheets("图库").Cells(h, l).Top '确定坐标
ileft = Sheets("图库").Cells(h, l).Left
iheight = Sheets("图库").Cells(h, l).Height '确定大小
iwidth = Sheets("图库").Cells(h, l).Width
For Each p In Sheets("图库").Shapes
If p.Name = pname Then
x = MsgBox("发现你的图库中已经存在同名图片，请确定是否为新图片？", stly, "图片重名，警告！")
If x = 7 Then
Exit Sub
Else
x1 = MsgBox("您确定需要替换名为：《" & pname & "》的图片吗？", stly, "图片替换,警告！")
If x1 = 6 Then
itop = Sheets("图库").Shapes(pname).Top
ileft = Sheets("图库").Shapes(pname).Left
iheight = Sheets("图库").Shapes(pname).Height
iwidth = Sheets("图库").Shapes(pname).Width
Sheets("图库").Shapes(pname).Delete
Else
chongshu:
If pnamewr = "" Then
pnamewr = InputBox("您尚未对图片命名，需要正确命名，方能插入此图片！", "图片命名")
Else
pnamewr = InputBox("您的图库已经存在以《" & pnamewr & "》为名称的图片，需要重新命名，方能插入此图片！", "图片命名")
End If
If pnamewr = "" Or pnamewr = pname Then
jinggao:
MsgBox "警告！输入为空或为同名！请继续输入", vbExclamation, "图片命名警告！"
GoTo chongshu
End If
For Each p1 In Sheets("图库").Shapes
If p1.Name = pnamewr Then GoTo jinggao
Next
End If
End If
End If
Next
ActiveSheet.Pictures.Insert(picname).Select
With Selection.ShapeRange
.Name = pnamewr
.LockAspectRatio = msoFalse
.Top = itop
.Left = ileft
.Height = iheight
.Width = iwidth
.Rotation = 0#
End With
End If
End Sub
2新建一个工作表取名为：“图库”。
3左键单击菜单：视图-工具栏-窗体，用窗体工具栏上的按钮控件，在图库工作表，左键拖拉画出一个按钮，名称改为插入图片，指定宏为picxz，然后随机插入几张图片。效果如下：
4 ALT+F11打开VBE编辑器，在ThisWorkbook中粘贴如下代码：

5当更改单元格内容或者因为计算而引起单元格内容变化时，将在对应位置更新图片，最终效果如下：
下面以jpg图片为例：
Sub lqxs()
Dim Filename$
Filename = Application.GetOpenFilename("JPG Files (*.jpg), *.jpg", , "请选取文件", , MultiSelect:=False)
If Filename <> "" Then
ActiveSheet.Pictures.Insert (Filename)
End If
ActiveSheet.Shapes(Application.Caller).Select
Selection.Delete
End Sub
1、要图片1显示图片2可用代码：
Image1.Picture = Image2.Picture
2、要让图片1不显示图片（无签名）可用代码：
Image1.Picture = LoadPicture("")追问
其实我真的很想给你最佳答案，简介精炼，就是我想要的，只可惜运行不出来。
追答给我个邮箱地址，我发个Excel给你测试
追问追答发过去了。代码没有错。收到了给我邮箱回个音。
测试界面在“Sheet1”，图像框 Image0为签名处， Image1、 Image2为预设签名，其中Image1、 Image2的Picture属性已预设为不同的签名。代码在“Sheet1（Sheet1）”模块。
单击Image0，可清除签名；单击Image1，使用Image1签名；单击Image2，使用Image2签名。
只有三个图像框，三个单击过程，每个过程只需一句代码。
Private Sub Image0_Click()
Image0.Picture = LoadPicture("")
End Sub
Private Sub Image1_Click()
Image0.Picture = Image1.Picture
End Sub
Private Sub Image2_Click()
Image0.Picture = Image2.Picture
End Sub
ActiveSheet.Shapes("Picture 1").Visible = False
Selection.InlineShapes.AddPicture FileName:="C:\图片2", LinkToFile:=False, SaveWithDocument:=True
