i do not believe a picture is an accurate representation of how any girl/women looks regardless if the person is photogenic or not.
Very simple solution:- Send in more than 1 picture:- e.g. 1 in your Yom Tov outfit, 1 in Shabbos outfit, 1 in work outfit, and 1 in casual attire. or some combination of this, and possibly 1 B & W picture.
This will give anyone a broader view of the back ground that you blend into.
