Success!
First, let me say I could never get the screenshot maker to work and this may have been part of my problem. Since I used an external player with its own screenshot maker I did not pursue the issue any farther. If I remember correctly the log indicated something like, unable to connect, or something like that. I thought it was probably a file association problem and gave it no further thought.
Anyway, here is what I did to get the image to appear, even though it was a strange solution.
I could not find the "screenshot box" Zacca was describing. It was unfamiliar to me as I had never seen this before. I tried various things unsuccessfully. My shotgun approach to finding a solution was not working.
While taking a shower it occured to me that maybe the screenshot extension was something other than a jpg. So, after drying off and dressing, I changed the extension to .png and imported the file into the poster box, because that was the only box available. When I did this I noticed the fields moving down the screen, leaving a large blank space at the top. While scrolling through this vast wasteland I saw another box which, as it turns out, was the screenshot box. I moved my cursor to this box and successfully imported a jpg file.
I'm not even going to try figure out how this might happened, but it does work and now I can get on to getting ready for Thanksgiving.
Thanks Rick and Zacca for your assistance
