** Description changed: The newly introduced Image Store UI in Eucalyptus relies on a local proxy in order to perform searches, queries, and to emit commands for - image downloading and installation. This proxy is still being written, - and has to be introduced next to Eucalyptus for the feature to work. + image downloading and installation.
