Formatting images without select

Question

I'm want to perform a variety of formatting options on images in slides.

The macro runs on images that I've SELECTED in a slide, but I'd like to run the macro without selecting the images.

Here's how I'm currently manipulating images (in this case aligning the image to the horizontal center of the slide) and the piece of code that I'm looking for help replacing:

With ActiveWindow.Selection.ShapeRange
 .Align (msoAlignCenters), msoTrue
End With

Here's the entire code body so far:

Sub TestCenterImage()
Dim osld As Slide
Dim oshp As Shape

For Each osld In ActivePresentation.Slides
 If osld.SlideIndex > 1 Then Exit Sub 'I don't know if I need this line
 For Each oshp In osld.Shapes
  If CheckIsPic(oshp) = True Then 'Making sure that we're only working with images
   With ActiveWindow.Selection.ShapeRange 'The portion of code I need help with
    .Align (msoAlignCenters), msoTrue
   End With
  End If
 Next oshp
Next osld
End Sub

Function CheckIsPic(oshp As Shape) As Boolean
If oshp.Type = msoPicture Then CheckIsPic = True
 If oshp.Type = msoPlaceholder Then
  If oshp.PlaceholderFormat.ContainedType = msoPicture Then CheckIsPic = True
End If
End Function

Try it this way instead:

Sub TestCenterImage()
Dim osld As Slide
Dim oShp As Shape

For Each osld In ActivePresentation.Slides
 'If osld.SlideIndex > 1 Then Exit Sub 'I don't know if I need this line
 For Each oShp In osld.Shapes
  If CheckIsPic(oShp) = True Then 'Making sure that we're only working with images
    CenterOnSlide oShp
   'End With
  End If
 Next oShp
Next osld
End Sub

Function CheckIsPic(oShp As Shape) As Boolean
If oShp.Type = msoPicture Then CheckIsPic = True
 If oShp.Type = msoPlaceholder Then
  If oShp.PlaceholderFormat.ContainedType = msoPicture Then CheckIsPic = True
End If
End Function

Sub CenterOnSlide(oShp As Shape)
    Dim sngSlideWidth As Single
    Dim sngSlideHeight As Single

    sngSlideWidth = ActivePresentation.PageSetup.SlideWidth
    sngSlideHeight = ActivePresentation.PageSetup.SlideHeight

    oShp.Left = sngSlideWidth / 2 - oShp.Width / 2
    oShp.Top = sngSlideHeight / 2 - oShp.Height / 2


End Sub
