Sorry, I read your PM early this morning and forgot to respond when I hit the office.
The easiest way to post a photo is to host it on a third-party server like photobucket or picture trail.
You copy the URL location that that service gives you for hosted photos.
Then you come here and hit the "attach photo" button in the editing control panel
and paste the link into the window that pops up.
That's how I inserted the picture of the button in this message.
