What a picture invite cannot do
The image card is quick and handsome, and then it stops. It cannot answer a question, so a guest who wants the parking details writes to you. It cannot collect a reply, so yes arrives as a separate message. And it cannot change, so when a friend forwards last month's version with the old time on it, the stale card quietly becomes the invitation people act on.
The fix is not to abandon the card look; it is to make the card open onto something. A digital invitation card built as a page keeps the design on the front and carries the schedule, the venue map, the reply button, and the photo space behind it. The same considered image, now with a working pair of lungs.
