How to customise photos, music and sections

The editor lists the sections in the order guests read them: the couple's names, both families, ceremony and reception times, venues, the photo gallery, RSVP, wishes and gift details.

Going through them in order means you miss less. Each time you finish one, glance at the preview to see the result straight away.

Scroll to the Photo gallery section and upload your wedding photos. You can select several at once, and drag them to reorder.

Upload after the text is done: by then you can see the template's real layout and tell which photo suits which frame.

Use bright, sharp originals. Photos re-downloaded from Facebook or Zalo are already compressed, so they look grainy once the card enlarges them.

Keep faces away from the very edge. Most templates crop automatically to fit a phone screen, so a photo with its subject near the middle is safest. After uploading, scroll the preview once to be sure no photo cuts off a face.

The Music section is where you pick the song that plays when a guest opens the card. Choose from the built-in list.

The card tries to start the music on opening. Many phone browsers block that, and when they do the card shows a small prompt the guest taps to start it. So do not worry if you hear nothing the first time you test it.

Not every wedding needs every section. Optional ones such as the gallery, wishes, RSVP and gift details can all be switched off.

When switched off, the section disappears from the card completely rather than leaving a gap. You can switch it back on at any time and your content is still there.
