A prepared slideshow is the one most people picture: childhood photos, awkward teenage haircuts, how you met, the proposal. You, a sibling, friends or parents build it weeks ahead, set it to music and play it once, with the whole room watching. It's a moment in the program, like a toast told in pictures.
A live slideshow works differently. Guests take photos during the day, share them from their phones, and the pictures loop on a TV or projector screen through the evening. Nobody sits down to watch it: people drift past, spot themselves at the ceremony an hour earlier and call their friends over. It's closer to a wedding photo wall display than a presentation.
They do different jobs. The prepared slideshow tells your story to people who only know part of it. The live one shows the day through your guests' eyes, including moments you and your photographer never saw. They don't compete, and plenty of couples run both.
