rating stars

Hello. Can I rate my articles on the site (stars) myself so that the rating is shown in Google results? Does Google see that the rating is artificial? I want to rate an article from my IP once, not 10 times.

I've been searching around lately and haven't been able to come across any free, simple scripts that will let me put a photo up on my site and then have a simple rating system where the user can rate it say 1-10 on a "hotness" scale... I know this should be a simple script but most I have...
