  1. Hi
    I hope to call you on the phone…what is your phone number and what time if best to call?
    and ask you to “walk” me through “Browser file DCIM” program that is present on my computer,
    and has “worked” in the past…………to transfer digital photos from CPU to “jeff’s ” e mail….

    It worked until Hotmail email “Updated” my program automatically, without my permission,
    and now I can’t “find” the menu selections that I formerly used to “send” these photos..😣

    I will call you after I take a couple more shots of fences etc. and select THREE to e mail…my transfer program will only transfer three and that’s OK with me as long as they are “dpix” size….


    Charlotte…”If I could get a grip on reality…I’d choke it…”
