Ricky at Maemo-Guru brings news of Hermes, a piece of software which, by pulling information from Twitter and Facebook, allows you to automatically add photos to your contacts. The software works by matching the names between the N900's contact list and your friends list on Facebook and Twitter. The software has been developed by Andrew Flegg, known as jaffa to the maemo.org community.
Hermes is, essentially, a quick way to add photos to your contacts, by pulling information from your Facebook and Twitter accout.
Contact thumbnails on the Contacts application. Thumbnails are also used for incoming calls, messages and chat.
