You can also subscribe to xml feed of new images added to the site and you will automatically be informed in your feed aggregator (such as google reader) when new images matching your terms are added, to get the feed URL just perform a search and the RSS icon at the bottom of the search results will link to the feed. more about this on our developers information page where developers can find more information about integrating the search into their application or website.
