 ## No support for Image Attribute Subpackets
 In about 99% of all use cases there are better photos to be found in Android's contact database. Photos from Android's contact database are displayed only if a key has been confirmed, otherwise this could lead the user into a false sense of security. It is also not clear what a certification of an Image Attribute Subpacket would semantically mean. This is not specified in RFC 4880. Other applications such as [Kleopatra](https://www.kde.org/applications/utilities/kleopatra/) also doesn't support this subpackets.
