I moved some about 500 images and movies from my external HDD to Pictures folder in Windows Vista. I remember on XP i use to see the thumbnails but in Vista it is not showing me the same in windows explorer. No matter i choose any option from the view style like medium , large icons etc, but it wont displays the thumbnail. Even thought changing template to the folder (Pictures and Videos) doesn't works. I have tried several other customization settings but my Windows Explorer only shows the generic thumbnail of a picture (cartoon mountains and seascape) for all images and Movies.
I have no idea left what i can do to fix the same. Somebody please help.
