Getting the customer avatar

Hello all,
I am wondering if there is a function that is used to retrieve the customer's avatar imageUrl.
I'm trying to display the customer 's avatar on the homepage. My logic is as follow:

if (customer is logged in )
{
  if (the customer has uploaded an his avatar)
   {
      customerAvatarImage.ImageUrl= GetAvatarUrl();
   }

}

I am wondering if there is a public function to get the customer avatar imageUrl. Please help.

Try the following code

var customerAvatar = NopContext.Current.User.Avatar;
if (customerAvatar != null)
{
  int avatarSize = this.SettingManager.GetSettingValueInteger("Media.Customer.AvatarSize", 85);
  string avatarUrl = this.PictureService.GetPictureUrl(customerAvatar, avatarSize, false);}
}

Thanks very much for your help!
