<mce:script type="text/javascript"><!-- jQuery(function() { jQuery('a[rel*=lightbox<%= GetPropertyID() %>]').lightBox({ imageLoading: '<%= Me.ResolveUrl("images/lightbox/lightbox-ico-loading.gif") %>', imageBlank: '<%= Page.ResolveUrl("~/images/spacer.gif") %>', txtImage: '<%= GetLocalizedValue("Image") %>', txtOf: '<%= GetLocalizedValue("Of") %>', next: '<%= GetLocalizedValue("Next") %>', previous: '<%= GetLocalizedValue("Previous") %>', close: '<%= GetLocalizedValue("Close") %>' }); }); // --></mce:script>
