This one will do all the words in column A as .jpg and all the words in
column B as .gif

Sub ConcatenateMeExtention()
Dim lastrow As Long, r As Long
Dim num1 As String
Dim num2 As String
lastrow = Cells(Rows.Count, "A").End(xlUp).Row
For r = lastrow To 1 Step -1
If Cells(r, "A") < "" Then
Cells(r, "A").Select
num1 = Selection.Value
End If
With ActiveCell
.Value = num1 & ".jpg"
End With
Next r

lastrow = Cells(Rows.Count, "B").End(xlUp).Row
For r = lastrow To 1 Step -1
If Cells(r, "B") < "" Then
Cells(r, "B").Select
num1 = Selection.Value
End If
With ActiveCell
.Value = num1 & ".gif"
End With
Next r
End Sub
