You could use a macro like:
Sub Demo()
Application.ScreenUpdating = False
Dim StrTxt As String
With ActiveDocument.Range
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.MatchWildcards = True
.Text = "C:*.[a-z]{3}>"
.Replacement.Text = ""
.Wrap = wdFindStop
.Forward = True
.Format = False
End With
Do While .Find.Execute
StrTxt = .Text: .Text = vbNullString
.InlineShapes.AddPicture StrTxt, True, True, .Duplicate
Loop
End With
Application.ScreenUpdating = True
End Sub
The above code inserts the pictures as linked images. Alternatively, to insert them as stand-alone images:
Sub Demo()
Application.ScreenUpdating = False
Dim StrTxt As String
With ActiveDocument.Range
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.MatchWildcards = True
.Text = "C:*.[a-z]{3}>"
.Replacement.Text = ""
.Wrap = wdFindStop
.Forward = True
.Format = False
End With
Do While .Find.Execute
StrTxt = .Text: .Text = vbNullString
.InlineShapes.AddPicture StrTxt, False, True, .Duplicate
Loop
End With
Application.ScreenUpdating = True
End Sub
