How to post data without visual interface?

Sorry,I did not find a better place to ask this.I don’t know that much about html and stuff,I do know something though,there is this site [url]http://www.rate.ee/show.php[/url] where you rate pics,and there is a box with radio buttons in it,when you click one of them it posts a rating to that picture,here is my question:
How could I post that rating without using my mouse to click.I know that this is what makes it work:

[code]<input type=”radio” name=”rating” value=”3″ onclick=”destroy_ten_div();if(pressed.value==0){pressed.value=1;this.form.submit()}”>[/code]

this for example rates a picture with a 3,I need to post the data somehow without even opening my browser,if you’re wondering why,then I am working on something.
