.net ajax slideshowextender

Jeg er igang med at lage med .net ajaxtoolkit, nærmere bestemt slideshowextender.

Selve slide show kommer op på siden, min webservice levere et array af slides (tilsyneladende) men, jeg kan ikke skifte billede/slide i ui eller sætte det til at køre automatisk... der sker bare ingenting.... kun default billede vises.

Her kommer lige noget kode så der forhåbentligt er nogen der lige kan gennemskue denne...

aspx - snippet...:
<asp:Image ID="RestaurantImage" runat="server"                                ImageUrl="~/Images/Hotels/hotellet1.jpg" AlternateText="Blue Hills image" />
                            <br />
                            <asp:Button runat="Server" ID="BackButton" Text="Prev" BorderColor="#FFAC11" BorderWidth="1" BackColor="white" ForeColor="#284775"
                    Font-Names="Verdana"/>&nbsp;
                            <asp:Button runat="Server" ID="PlayButton" Text="Play" BorderColor="#FFAC11" BorderWidth="1" BackColor="white" ForeColor="#284775"
                    Font-Names="Verdana"/>&nbsp;
                            <asp:Button runat="Server" ID="ForwardButton" Text="Next" BorderColor="#FFAC11" BorderWidth="1" BackColor="white" ForeColor="#284775"
                    Font-Names="Verdana"/>&nbsp;
                            <ajaxToolkit:SlideShowExtender  ID="slideshowextend1" runat="server" TargetControlID="RestaurantImage"
                                SlideShowServiceMethod="GetSlides" SlideShowServicePath="~/Services/GetSlidesService.asmx"
                                AutoPlay="true" NextButtonID="ForwardButton" PlayButtonText="Play"
                                StopButtonText="Stop" PreviousButtonID="BackButton" PlayButtonID="PlayButton" Loop="false" />
