<sf:ResourceLinks ID="resourceLinks1" runat="server" UseEmbeddedThemes="false">
<sf:ResourceFile Name="~/CustomImageGallery/FancyImageGallery.css" Static="true" />
<sf:ResourceFile Name="~/CustomImageGallery/fancybox/jquery.fancybox-1.3.4.css" Static="true" />
</sf:ResourceLinks>
<ul>
<asp:Repeater ID="ImageRepeater" ItemType="Telerik.Sitefinity.Libraries.Model.Image" runat="server">
<ItemTemplate>
<li>
<a class="grouped_elements" rel="group1" href="<%# Eval("MediaUrl") %>">
<img class="thumbImg" src="<%# Eval("MediaUrl") %>" alt="image" />
