So, after a re-start, the thumbnails start showing up correctly? If so, there is nothing wrong with the photo itself, otherwise you'd never see a thumbnail at all for that photo. If not, there is something wrong with the photo, in which case attaching one of the non-working photos would hep.
Also please let me know whether killing and re-starting the gallery app fixes it.
