Multi-photo Select & Caption
When I first started, the photo sharing experience on Messenger didn't give people control over how they want to communicate. Only one photo can be selected at a time. Captions need to be sent separately. Since text messages are sent faster, caption might get sent first before the photo and creates a confusing message for the recipient.
In the prototype above, people can select more than one photo to send in a single message. I've seen behaviors like this when people want to keep their family Messenger updated when they go on a trip by sharing the most recent vacation photos.
Additionally, people can add a message to go with the photos. That way, they can use the message to explain the photo(s) and the entire message will appear at once.
A picture is worth a thousand words! We saw a steady interest in visual messaging and wanted to encourage people to communicate using photos (instead of text). However, taking a photo to respond requires a lot of steps and it's much faster to bring up the keyboard, type a message, and hit send.
I hacked together a quick concept that makes responding with a photo as lightweight as possible. In this design, when someone sends me a photo, there's a CTA to reply with a photo. When I tap on that button, a mini Camera appears within the messaging window. I can simply take a photo from there and hit send.
