Pictures don't show up in Windows7

Problem: In folder My Pictures, pictures have no display image, only default icon instead

Start - Control panel - System -
Advanced System settings (AKA System properties) -
Advanced - Settings - Visual effects at Performance options:
Show thumbnails instead of icons
uncheck it - apply - and then check it again -ok
