Thanks. Actually, I figured it out. I assumed it was just a matter of creating a link to a web site where you posted a picture that was less than 70K...well, I found out this was correct. Then I just uploaded a small photo, copied the URL link, and then typed in .jpg at the end.
I received an email from a person the other day who said it would be nice if folks could post a photo near their signature so we would get to put a face with a thread. I thought this was a nice idea. I was going to do something fancy...you know, like wear a helmet, camouflaged fatigues, etc., but then I snapped out of it!
