Xara Layering is very powerful. To navigate around the images, use Previous button - popup: close "LayerN" open "LayerN-1"; Next button - popup: close "LayerN" open "LayerN+1" or a button menu (Names, Numbers, Thumbs). Thumbs can be added under all layered images with Links to the layers (& Transitions). I am sure there is some Javascript code to automate a slideshow. siran?
Possibly use an embedded Presentation site.
Always Name your big images.
