The following variation on the macro from the linked thread shows how you might achieve what you're after. As coded, it uses fixed 2cm column widths and 1.5cm row heights. Transparencies are also set.
Code:
Sub AddPicsNoCaption()
Application.ScreenUpdating = False
Dim i As Long, j As Long, c As Long, r As Long, NumCols As Long, iShp As InlineShape
Dim oTbl As Table, TblWdth As Single, StrTxt As String, RwHght As Single, ColWdth As Single
On Error GoTo ErrExit
NumCols = 7
RwHght = CentimetersToPoints(1.5)
On Error GoTo 0
'Select and insert the Pics
With Application.FileDialog(msoFileDialogFilePicker)
.Title = "Select image files and click OK"
.Filters.Add "Images", "*.gif; *.jpg; *.jpeg; *.bmp; *.tif; *.png"
.FilterIndex = 2
If .Show = -1 Then
'Create a paragraph Style with 0 space before/after & centre-aligned
On Error Resume Next
With ActiveDocument
.Styles.Add Name:="TblPic", Type:=wdStyleTypeParagraph
On Error GoTo 0
With .Styles("TblPic").ParagraphFormat
.Alignment = wdAlignParagraphCenter
.KeepWithNext = True
.SpaceAfter = 0
.SpaceBefore = 0
End With
End With
'Add a 1-row by NumCols-column table to take the images
Set oTbl = Selection.Tables.Add(Range:=Selection.Range, NumRows:=1, NumColumns:=NumCols)
With ActiveDocument.PageSetup
TblWdth = .PageWidth - .LeftMargin - .RightMargin - .Gutter
ColWdth = CentimetersToPoints(2)
End With
With oTbl

.Borders.Enable = True
End With
For i = 1 To .SelectedItems.Count Step NumCols
r = ((i - 1) / NumCols + 1) * 2 - 1
For c = 1 To NumCols
j = j + 1
'Insert the Picture
Set iShp = ActiveDocument.InlineShapes.AddPicture( _

SaveWithDocument:=True, Range:=oTbl.Cell(r, c).Range)
With iShp

.Fill.Visible = False
.LockAspectRatio = True
If (.Width < ColWdth) And (.Height < RwHght) Then

End If
End With
If j = .SelectedItems.Count Then Exit For
Next
'Add extra rows as needed

End If
Next
With oTbl

.Columns(1).PreferredWidth = CentimetersToPoints(2)
.Rows.Alignment = wdAlignRowCenter
End With
End If
End With
ErrExit:
Application.ScreenUpdating = True
End Sub
