How do I rename photos or add a caption?

After you have uploaded one or more photos to a profile, whether this is a Property, Zone, Asset or one of the People sections, and you expand the photo there will be a section at the bottom with the upload time stamp and name.

There is also a pencil icon that you can click to change the name and add a caption. Within this caption you can use rich formatting and tag and link other information in Nines. Right now this only works for profile photos in gallery view, but soon also for photos that have been uploaded as attachments to Protocols, Tasks, Lists, Logs, Comments, etc
