Love the photo, Steve!! Tried to add one of mine, put couldn't figure it out. I'll read back over all of the instructions and try again some other time.
What I tried was click reply, then clicked on the little paperclip on the reply window. When that brought up another window, I clicked on browse to upload file from your computer, found the pic I wanted to upload, and told it to upload. It started, then seemed to get stuck part way through. I don't know what I was doing wrong. I've got dial up. Maybe the file was just too big? Oh well, as a nearly 60 granny, I think I'm doing pretty good to do the things I do manage to do.
