Ken,
Pics end up inline with the msg, text anywhere I want to put it. Ergo:
Interesting that it looks inline while you're composing the message.
Your message arrived at Groups.io (and my email inbox) with only two elements: a text/plain message body and the image/jpeg attached photo.
I don't know if there's an option you could have used to change that. Gmail (including on Android) tends to send messages as text/plain only if you just type out text, it only switches to multipart/alternative to include an HTML formatted part if you use the text formatting tools.
I'm not sure if I can embedded my own pictures inline in Gmail on Android; I don't see the UI elements to do that.
Shal
