Since LayerSlider WP 3.0, you have an option to deep-link a layer. This is means that you can give a special URL to your users that will open LayerSlider with the desired layer on start. To do that, you have to specify a deeplink name in your Layer Options and reference in the URL with a hash mark followed this name.

For example if you added the name for the deeplink field "surprise", you can reference this layer with the URL "".

Please note that we changed the deeplink method in LayerSlider WP 3.5, the old method used IDs, this is no longer supported.
