If you are pretty dont put your photo in your CV (Abu Dhabi)

I started a forum on Linkedin where I was complaining about I am so sick that I send my CV to lots of companies and the only answers I got back is marriage proposals (or sexual proposals). One person told me that I must not put my photo in my CV because I look pretty on it.

What do you think about this? If you are a woman and you want someone takes you seriously you have to look ugly in your CV?
