Like button for a post

Hello, is there is any way I could make a like button just like this after every post on my forum? And that people could actually click on it, and it would count likes? Sorry for my bad english, its not my main language, but I hope you will understand what I want to say.

Hi @dianka,

See if any of these tutorials fit what you're looking for :
A New Like/Dislike System
Improve the reputation system so it counts votes

Thank you I used the first tutorial, also is there is any way I could add emoticon image to the button and make it transparent (without blue background)? And also when I click the like button on a post it's just shows loading, but dosen't add the like to the post.
