For a while there, SA allowed users to add photos to their messages.  (Different photos from those posted.)  I wanted to do that recently but I don't see how.  Did they remove that capabili8ty or am I missing something?

Should be on the bottom left next to the chat box for you to type in.

I see it now, thanks!  The icon disappears as soon as you start typing a message, so I guess you have to add pics before you start writing.
