Option to open on 1st slide in light box

I’ve tried everything I could think of (from slider, from image, altering meta slider lightbox code…), and I’m good at missing stuff… Is there a simple possibility to launch a meta slider in a lightbox (I use Simple Lightbox but tried with others) pointing to the first slide, either launched from an image or same meta slider?

Thanks.
