Hi ShSimpson,
On the assumption the pictures aren't in-line with the text, you could use a macro like:
Code:
Sub Reformat()
Application.ScreenUpdating = False
Dim oShp As Shape
For Each oShp In ActiveDocument.Shapes
With oShp
.ScaleHeight 0.75, False
.ScaleWidth 0.75, False
End With
Next oShp
Application.ScreenUpdating = True
MsgBox "Finished Reformatting."
End Sub
Note that this will resize
every kind of non-inline shape in the document.
