Hello chapolote,

Thank you for getting in touch with us. My name is Attila and I'm happy to assist you today. I appreciate your patience while we've been working towards your ticket.

I believe the slideChangeDidComplete event would be sufficient for what you're trying to achieve. But you can find every event and method available with description on the following URL: https://support.kreaturamedia.com/docs/layersliderwp/documentation.html#layerslider-api So you can look around if there's another that fits your needs.
