I'm assuming this (http://en.battlestarwiki.org/wiki/Tattoo) is the one you saw at BSG wiki? You can see half of it in Katee's promo image (http://pics.livejournal.com/drewcypher/pic/000f16z6/g186), but not the full thing. This (http://pics.livejournal.com/drewcypher/pic/000hy3rh/g216) promo shot of Anders shows what's missing in Katee's promo shot.

There's probably a better/larger screencap or picture of it out there, but that's all I can think of right now. Hope it helps a bit, at least. :)
