Need custom Wordpress plugin for RSS feed auto-blogging

I need an auto-blog plugin for Wordpress that will post information coming from an RSS feed provided by iStockphoto. I am a photographer for iStock, and I contribute new photos every day. So I very much want an automated process to take the images and all relevant information from the RSS feed associated with my account and post daily to my Wordpress blog, along with all relevant keywords from the associated web pages (and synonyms if possible) in a fashion that is NOT considered spam by Google and other search engines. My goal is to increase search engine visibility for my images and portfolio.

Each image should be a separate post (not multiple images on one page), and I would like to be able to custom configure the number of posts per day.

Here is a link to my RSS feed:
