I downloaded the YT clip in high resolution, found a good shot of Marin, did a screencap, pasted it into Photoshop, increased the contrast, used the magic wand tool to select and remove most of the surrounding stuff, did an oval-marquee select, pasted that into a new image, cleaned it up a bit more, used the blur tool on the edges of her hair, shrank it down to the proper size, converted it to a GIF, and made the surrounding white the transparent color. I'm pretty crude with photoshop, so it's a bit sloppy, but OK, I guess. Then I posted it to my image hosting service.
There are people here who could have done the whole thing, added animation, and made it look much nicer, all in less than five minutes (it took me closer to 15). ^^I suspect that she'd be inclined to give diplomatic answers to questions of that sort in any event -- privacy is hard to come by these days (even for us non-celebrity types), but it's usually more comfortable to maintain at least some kind of firewall between one's public and private lives.
