(WORKAROUND) create a meeting (Photos and Stuff) to your self. Join the meeting and post a comment. End the meeting. Now pin the meeting chat and you should be able to post text and photos the the meeting chat and they will show up in the chat for the meeting on all your devices.
We used the meeting feature to complete a photo site survey. After the meeting everyone assigned to complete a survey of a site just posted the photos to the meeting chat from their phone. Worked like a charm. :-)
