RSS assistance

I have built up my following on twitter to about 4,000 in the music genre. I have lots blogs that potentially i could post directly to, but i have a newbie question. How can I do what the pirate warez blogs do with RSS, how do they feed in the RSS with pictures and the download links, I know they don't do it manually. My plan is to get others to post code that will do that on their blogspot blogs, so that posts from my blog, will end up showing up on their blog without them having to repost. because that is a pain in the ass. I'm hoping some hacker types might know how it works, an point me to a tutorial on building a warez blog, but i'm not posting warez, I'll be posting music made by unsigned artists. thanks in advance.
