Found on the server, a picture send by an anonymous :

Could it be for Battlestar Galactica ?
Did someone mention that contribution on imcdb or on the forum ?

I don't remember any post about it here in contributions.

As you say could be for the 1978 Battlestar Galactica

buy also for the Galactica 1980 http://akas.imdb.com/title/tt0080221/

Only one pic by an 'anonymous' (user?) with no IMDB link and with no role (or at least seen in trailer), I think it's better [N/A] for a MG with actually 4 pages in the site.

It appears to be from the show "Galactica 1980." If I remember correctly, it involved present day (in the 1980s) Earth. The NBC logo in the corner leads me to believe that it came from a video website like Hulu.com. Unfortunately, Hulu no longer carries "Galactica 1980," so I can't look at the episodes and check.
