I need help decorating! Any good websites?

I moved into my boyfriends house about a year ago and am sick of his lousy decorating. I haven't wanted to spend time/money changing anything because we keep talking about moving, but I can't take it anymore. His idea of decorating is sports posters in the living room. I have never had my own house to decorate and don't know where to start! Any good websites with pictures to inspire me? I need websites showing REAL ideas, not picture perfect pottery barn homes! I'm looking for ideas for window treatments (because we have big wrough iron radiators under the windows, it's an old house from the 1800's) and wall decor, paint colors, etc.

Thanks!
