Bots are only able to post text messages to rooms, however, it would be convenient if bots were able to attach photos as a message to the room.

We would prefer if our bot didn't have to upload images to an accessible URL and then post that url to the room (and then only get a preview of an image), as this adds a few extra steps to viewing the image and requires our bot to be aware of when it is done uploading the image to the host and then finally post the link to the room.
