Automatically post website content to my facebook page

I have flash game website for kids and want to automatically push content to its facebook fan page after the content is published on the website. Currently we were using RSS Graffiti, which gets the job done, but if you can provide me a script that can be uploaded to my server, so that i won't have to use 3rd party software that would be great. I want to include your code into my posting content page. This is a good example of RSS Graffiti: [login to view URL] The script should be able to post to a page like that. Also please let me know if it is possible to increase the size of the images. My budget is 20$-30$ for this project. I hope it's fairly easy for someone who has already done this.
