Big animation

[Raknarg]

So I have this task in class to make an animation. I have about 248 slides (starting from 0) that I'm using for it. This is what I have so far:

VisualBASIC:

Public Class Form1     Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick         Do             For i = 0 To 247                 If i < 10 Then                     Me.Picture.Image = New System.Drawing.Bitmap("P:\Pivot Files\martial arts00" + Str(i) + ".bmp")                 ElseIf i < 100 Then                     Me.Picture.Image = New System.Drawing.Bitmap("P:\Pivot Files\martial arts0" + Str(i) + ".bmp")                 Else                     Me.Picture.Image = New System.Drawing.Bitmap("P:\Pivot Files\martial arts" + Str(i) + ".bmp")                 End If             Next         Loop     End Sub End Class

My issue is that whenever I put Str(i) inside the brackets, it tells me "This parameter is not valid. I've taken it out and it works. Any help here?

The reason i do it this way is so that I dont have to import over 200 pictures.
