This article describes the configuration of the experiments that we submitted for the ImageCLEF Photographic Retrieval Task. We used a redesigned version of our last years retrieval system prototype (see [1] for details). The translation of the topics for our cross-lingual experiments was realized with a plug-in to access the Google Translate [2] service. We used thesauri from OpenOffice [3] to expand the queries for better retrieval performance. This year, we submitted 11 runs, whereof only
