Honestly, as a person from that type of community, they probably didn't consider whether or not she was a convert, there are plenty of Asian converts these days, but rather the fact that she was wearing pants, which tends to immediately raises blood pressure among the right wing elements. My guess is that the pants were more at issue than the conversion status when the choice of photos was made. Outsiders to Modern Orthodoxy don't always get these insider issues (pants and sleeves on women, mixed swimming, certain types of haircuts, etc. In the traditional community, the kind of black hat one wears is a signifier of community, so don't get a black hat with a feather on the brim, if you want to fit in!)
