I have mixed feelings on this, in one case I agreed to go out with a girl before I saw pictures of her and then I saw some pictures before the first date and it made me a lot less excited to go on the date. When I actually saw her in person I wasn’t even sure she was the same person, she was so much better looking, it was just a bad picture. On the other hand the last girl I went out with did not provide a picture, and if she had I might have saved her time and feelings by not going out in the first place.
In general if you don’t provide a picture it will be assumed that there is something you’re trying to hide. I’m not saying that it’s fair and maybe the system should be changed but you probably shouldn’t try to change it by yourself b/c it could hurt your daughter in the meantime.
