Custom Image not found during exec terraform script

We have some problem creating a datacenter with terraform scripts. If we used ProfitBricks Images like "ubuntu-16.04", it's all fine. But if we used custom images, we uploaded to the same datacenter location, we get the error that the image cannot found. Have anyone a idea whats here the problem? Is it possible to use custom images in terraform scripts? We have successful used the custom image creating a Volume in the DCD.

Could not find an image/imagealias/snapshot that matches BaseImage_16_04

resource "profitbricks_server" "testserver01" {
  name              = "testserver01"
  datacenter_id     = "${profitbricks_datacenter.datacenter01.id}"
  cores             = 4
  ram               = 16384
  availability_zone = "AUTO"
  cpu_family        = "AMD_OPTERON"

  volume {
    name           = "system_volume-01"
    image_name     = "BaseImage_16_04"
    size           = 10
    disk_type      = "HDD"
    ssh_key_path   = ["${var.public_key_path}", "${var.public_key_path_intern}"]
    image_password = "${var.volume_password}"
  }

  nic {
    ....
  }
}

Thanks Michael
