I spoke to an hot girl at lecture and I have a date with her on Saturday

I spoke to a girl at lecture today, we chatted for a minute and then I asked her out on a date. She said yes! I'm not sure whether to be excited or nervous. I'm 26 and this is my first ever date. I've read some online dating profile tips and One of online dating tips is "send her your real photo, so she knows this is not a catfishing thing; she will trust you from the beginning when you do it." I'm planning on sending her a face pic of me because I'm legit scared if I don't. I'm really afraid if she doesn't want me anymore if she knows what I look like. Please advice me on this.
