I am seeking a plugin for enhancing my blogs page is ther

I am seeking a plugin for enhancing my blogs page is there some type of plugin or programming that I can get to make my blogs page for fluffey.com able to have photos upload on them. Another words what I think would be a great idea is to have a plugin for allowing blogs to have more than just comments. Something that will change the blogs to were people can make a small web page of their own. That users would be notified when someone in the network creates a new blog. This is called reproductive marketing. I could be making a bad mistake by saying this so you can steal vinnys ideas for fluffey.com. I am sure it is not anything new because I have a site that dose this already only it dose it in a different way. Is there any help for me I need this done can anyone help me.

Regards Vincnt Juliano I can come up with some great ideas.
