This is the heart of it: the image becomes the invitation, and the picture itself is the link. Upload a photo that means something to you both, or pick from the Hero Library dropdown.
Blank line = new paragraph. Paste links — they become clickable automatically. Keep the texted part short; the bottle carries the weight.
Open Additional Options: extra photos and animated GIFs with [Insert] chips, one video, link buttons, colors, fonts, animations. All optional — the default look is already right.
Lifetime: 24h to Forever (default 48h — bottles that drift away feel special). Replies on or off. Preview-card toggles next to Recipient and Title.
Hit Create. Copy the link or use Share, text it, done. Watch My Bottles for the moment it's opened — and for the reply.
