the thing is with that code is that it isnt adding a key(i need to remember what the key is for that pic cos i need it in other places), ive modified the code a bit see below: however it adds one image and displays it but when i try to add another the pic stays the same.

    Private Sub btnAddPic_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddPic.Click
        '     Dim temp As String
        '    OpenCustomerImage.ShowDialog()
        '   temp = OpenCustomerImage.FileName
        '  ilistNo = frmMain.ilistNo
        '
        '       Dim theImage As Image = Image.FromFile(temp)
        '      frmMain.iList.Images.Add(ilistNo, theImage)
        '     picCustomer.Image = frmMain.iList.Images.Item(ilistNo)
        '    ilistNo = ilistNo + 1
    End Sub

Debug 'ilistNo' variable, make sure about its value. The image key is type String (both with Add and Item), I don't know what your 'ilistNo' is, but it looks like a integer number, in which case you are setting this implicitly as string key, but when accessing Item you are actually getting it by integer index and not string key lookup.
