My apologies to the list. I was trying to reply to Lillian's query about photo numbering systems and inadvertently sent the 'reply' just to her. Some mailing lists allow a 'reply' to the list, some do not. Clearly, this one does not. When I discovered what I had done, I then 'forwarded' those messages to the list. This produced messages with lots of computer garble. Sorry. Next time I won't reply to queries until after my 2nd cup of coffee. DICK FOLKERTH Dallas
