It might help if you add an event handler to BackTrackButton1_Click

ohh that only because i copied this code after giving up and Deled the control in a rage :P so it was their and stil didnt work

[mandai]

The code should be changing the picture. If you try setting the picturebox image to the resource does it work?

'========================================================'
' i tried to change the code, i used a timer and and change the
' PictureBox1.Image = imgList(r.Next(1, imgList.Count)) to
' PictureBox1.BackgroundImage = imgList(r.Next(0, imgList.Count))
'pictureboxperperties-change to zoom
'=========================================================
'========here's the new code================================

Private Sub BackTrackButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
timer1.start
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim r As New Random
PictureBox1.BackgroundImage = imgList(r.Next(0, imgList.Count))

'This code (down) is optional- it rotate the image in picturebox
PictureBox1.BackgroundImage.RotateFlip(RotateFlipType.Rotate270FlipXY)

End Sub

just use a timer then the button is used to start the timer, as soon as the timer starts it play the images randomly, but you need to change the

PictureBox1.Image = imgList(r.Next(1, imgList.Count)) to

PictureBox1.BackgroundImage = imgList(r.Next(0, imgList.Count))


or else the first item wont be included in the random play.
and set the picturebox properties to zoom.
