An argument could be made that Google has over-indulged in its creation of way too many messaging apps in years past. But today’s launch of a new messaging service — this time within the confines of Google Photos — is an integration that actually makes sense.

The company is rolling out a way to directly message photos and chat with another user or users within the Google Photos app. The addition will allow users to quickly and easily share those one-off photos or videos with another person, instead of taking additional steps to build a shared album.
