Created and posted some new custom thumbnails in a client's YouTube account and they showed up fine in Google search results for about two days. Suddenly, some of them don't show - although the listings themselves show - but some of them still do show and I can't figure our why. The client is a criminal defense attorney. About the only thing I can think of is that the thumbnails that don't show have pretty girl photos and the thumbnails that do show have male photos, all licensed from $1 photo. The pretty girl images are not racy, e.g. girl with champagne glass for DWI video; girl giving thumbs up for reviews video, etc. The male images are relevant, e.g., police officer, guy in handcuffs. Haven't seen any references to this problem anywhere. Suggestions and observations appreciated.
