Hi
I have a scenario where a 30 images are uploaded
Code:

AnnotationService.prototype.loadAll = function (showAll) {
            var automationInteractiveMode = new lt.Annotations.JavaScript.AutomationInteractiveMode();
            var interactiveModes = [
                automationInteractiveMode,
                new lt.Controls.ImageViewerPanZoomInteractiveMode(),
                new lt.Controls.ImageViewerNoneInteractiveMode(),
                new lt.Controls.ImageViewerCenterAtInteractiveMode(),
                new lt.Controls.ImageViewerZoomToInteractiveMode(),
                new lt.Controls.ImageViewerSelectItemsInteractiveMode()
            ];
            var imageViewerDiv = document.getElementById('imageAdapterAll');
            if (imageViewerDiv == null) {
                imageViewerDiv = document.getElementById('imageAdapter');
            }
            var widthHeight = getDisplayHeightWidth();
            var numPages = AnnotationService.mediaReviewModel.contexts.length;
            var sections = numPages / 2;
            var height = widthHeight.height * sections;
            $(imageViewerDiv).height(height);
            $(imageViewerDiv).width(widthHeight.width);
            var createOptions = new lt.Controls.ImageViewerCreateOptions(imageViewerDiv);

            var verticalLayout = new lt.Controls.ImageViewerVerticalViewLayout();
            verticalLayout.columns = 2;
            createOptions.viewLayout = verticalLayout; //new lt.Controls.ImageViewerSingleViewLayout();
            
            AnnotationService.imageViewer = new lt.Controls.ImageViewer(createOptions);
            AnnotationService.imageViewer.zoom(lt.Controls.ControlSizeMode.fit, 1.0, AnnotationService.imageViewer.defaultZoomOrigin);
            AnnotationService.imageViewer.scrollMode = lt.Controls.ControlScrollMode.auto;
            AnnotationService.imageViewer.useElements = true;
            //AnnotationService.imageViewer.viewLayout = verticalLayout;

            loaditems(AnnotationService.imageViewer);

            AnnotationService.imageViewer.postRender.add(function (sender, e) {
                counter++;
                if (counter == numPages) {
                    alert("loaded post render...");
                }
                
            });

            var renderingEngine = new lt.Annotations.Rendering.AnnHtml5RenderingEngine();
            var manager = new lt.Annotations.Automation.AnnAutomationManager.create(renderingEngine);
            manager.createDefaultObjects();
            manager.editObjectAfterDraw = false;

            manager.createDefaultObjects();

            var hiddenAnnTools = document.getElementById("hiddenAnnTools");
            var automationObjCount = manager.objects.count;
            for (var i = 0; i < automationObjCount; i++) {
                // Get the object
                var automationObj = manager.objects.item(i);

                // Add its name to the select element
                var name = automationObj.name;
                var id = automationObj.id;
                hiddenAnnTools.options[hiddenAnnTools.options.length] = new Option(name, id);
            }


            manager.userMode = lt.Annotations.Core.AnnUserMode.design;

            AnnotationService.automationControl = new lt.Annotations.JavaScript.ImageViewerAutomationControl();
            AnnotationService.automationControl.imageViewer = AnnotationService.imageViewer;
            automationInteractiveMode.automationControl = AnnotationService.automationControl;
           
            AnnotationService.imageViewer.interactiveModes.beginUpdate();
            for (var i = 0; i < interactiveModes.length; i++) {
                var mode = interactiveModes[i];
                mode.isEnabled = false;
                if (mode.name == 'SelectItems') {
                    (mode).selectionMode = lt.Controls.ImageViewerSelectionMode.single;
                }
                AnnotationService.imageViewer.interactiveModes.add(mode);
            }

            AnnotationService.imageViewer.interactiveModes.endUpdate();
            AnnotationService.imageViewer.interactiveModes.enableByIndex(0);


            AnnotationService.activeAutomation = new lt.Annotations.Automation.AnnAutomation(manager, AnnotationService.automationControl);
            AnnotationService.imageViewer.itemChanged.add(function (sender, e) {
                var container = AnnotationService.activeAutomation.container;
                container.size = container.mapper.sizeToContainerCoordinates(AnnotationService.imageViewer.imageSize);
            });

            hiddenAnnTools.addEventListener("change", function () {

                var id = parseInt(hiddenAnnTools.options[hiddenAnnTools.selectedIndex].value);
                // Set it as the current object in the manager

                if (id != -1) {
                    AnnotationService.lastSelectedValue = id;
                }
                manager.currentObjectId = id;

            });

            AnnotationService.activeAutomation.active = true;

            AnnotationService.imageViewer.activeItem = AnnotationService.imageViewer.items.item(0);
        }

var loaditems = function (imageViewer) {
            var baseUrl = window.location.origin;

            AnnotationService.imageViewer.beginTransform();

            for (var i = 0; i < AnnotationService.mediaReviewModel.contexts.length; i++) {
                var currentUrl = baseUrl + '/' + contexts[i].sv.fileName;
                var item = new lt.Controls.ImageViewerItem();
                item.url = currentUrl;
                AnnotationService.imageViewer.items.add(item);
            }

            AnnotationService.imageViewer.endTransform();
        }

I have posted a How To post for loading multi-page annotations, that may give you a possible way to accomplish your task. The project uses AnnCodecs to load the annotations from an XML file to add the annotations to each ImageViewerItem along with the corresponding image and gives you the ability to navigate from page to page.
