OK, I'm not the brightest crayon in the box with computes/electronics/apps etc... I exceeded my own expectations when I learned to upload and post photos here but since my last posting of photos, which I could not open after posting them but others could, I cannot open ANY photos posted here! blink blink! Also, all photos, including those in my folder and the last I posted, have an "X" on them. What did I do to cause this, and more importantly - WHAT can I do to correct it???
