How to show hidden objects/images on slide show

[JustSayHi]

I have hidden image in one slide that i want to set click button to show the hidden image on present. Can any one help me?

1) Add (Disappear) animation to the image, and set it to start (With Previous).
2) Add another animation to the same image (Appear) from (Add Animation), (NOT FROM ANIMATION MENU).
3) Draw a shape or insert an image... to set it as buttom, and use (Trigger) to begin the second animation (Appear).

You can only do that with code.

Sub showHidden()
'NOTE this is ONLY for use in show mode
'NOTE the shapes will be visible when you finish the presentation
'The second code block fixes this it will run automatically
Dim osld As Slide
Dim oshp As Shape
Set osld = SlideShowWindows(1).View.Slide
For Each oshp In osld.Shapes
If oshp.Visible = False Then
oshp.Visible = True
osld.Tags.Add "TARGET", "YES"
oshp.Tags.Add "VIS", "NO"
End If
Next oshp
End Sub

Sub OnSlideShowTerminate(SW as SlideShowWindow)
Dim osld As Slide
Dim oshp As Shape
For Each osld In ActivePresentation.Slides
If osld.Tags("TARGET") = "YES" Then
For Each oshp In osld.Shapes
If oshp.Tags("VIS") = "NO" Then oshp.Visible = False
Next oshp
End If
Next osld
End Sub
