The site doesn't have every frame, but most moments that one might want to use. Bare in mind, since there's no HD transfer of DS9 or VOY, you're just as well off on image search.
Sorry, for the quality. It was the only screenshot I’ve found. In this shot from “Man of the People”, you can clearly see the dress/nightgown Marina Sirtis is wearing is highlighting her nipples.
FYI, Sirtis has stated in interview(s?) that she was aware that she was the sex symbol for the show.
Poor woman I remember in one interview she mentioned the outfit they gave her (up until Jellico made Troi start wearing a uniform) was so fitted that she couldn't gain a single pound.
She was in a couple Cannon company explotation films in her early career. She has thanked the show for getting her out of that explicitly abusive part of the industry.
Sometimes I think the future is bleak and nothing good with happen again. Then star trek shows me that there is hope, for... Humanity or something, yeah.
