A good profile picture can help you to be chosen more often!
The profile image must be a picture of you who owns the account. One tip is to take a picture of you with your vehicle in the background. This will make it easier for the advertiser to assess whether you get fit with the items in your car. Did you know that a smile on the picture can give a positive and nice impression that will help you getting chosen?
It is alright to be more people in the picture if you usually have a friend that help you, as long as you as an owner of the account have the focus in the picture.
