I tried the second time. It sent the photo and left the message in edit mode.
Now that you mention it, I think that is what I tried and experienced with the store-front photos I sent today. In this case, the full app would be FTN-friendly if a message can accompany the photo/file in one post. What I really like is that on the TgM side, all the photos that have ever been sent from the app are maintained in convenient folder.
