Idee

Upload ins Mediawiki via möglichst einfach gehaltenem Bash-Skript. Konstruiert, um via N900 direkt aus der Kamera-App Bilder hochzuladen

Anforderungen

Bash, Wget Sed, Grep mktemp

Hack-Faktor

Baut ein MIME multipart/form-data für wget, das das eigentlich nicht kann... Dürfte auch der Schwachpunkt der ganzen Angelegenheit sein...
