Norm,
This would be an exelent opportunity for someone like you, who hasn't published a picture, to teach yourself how and then weite a tutorial on how a novice can publish on this board.
After all, "What's so hard about uploading pictures?"
I find it is similar to many projects, one can explain but until the person actually experiences the process, execution will remain a mystery. The preview screen worked for me but it took looking at the "properties" of a successful post and several tries before I was able to post my first "picture".
Maybe your tutorial will help all of us....
