lightsystem

The plugin is configurable letting you define what feeds to read and how often to read them. It also lets you decide whether you want to store the external images locally, inserting them into the media gallery, or otherwise simply hotlink them (that is the default).
You will find these settings in your administration page on the Settings->RSS Settings sub-menu.
