It is a good idea to add a picture to your profile. Profiles with pictures are viewed more often than profiles without pictures.
Surprisingly many landlords prefer to search for tenants rather than posting a rental advert, and to them, photos are important.
You can say that search profiles without pictures are as attractive as rental ads without pictures.
Then you can either add your facebook profile picture or upload a picture from your device. If you already uploaded a picture, you will be able to delete it from here as well.
