My thumbnails used to show a small version of the photo so that I could see
which photo it was before opening them up. It has now changed and the
thumbnails only show me the picture manager logo. I now have to open each
and every thumbnail to find a photo whihc is very annoying. I am not sure
how to change it back to the way it was before? I have gone into view and
changed the view to list and large icon etc but they all still show me the
picture manager red logo until I open them up.

Any help greatly appreciated!
