Flexible jQuery Star Rating Plugin – jRating
jRating is a very flexible jQuery plugin for quickly creating an Ajaxed star rating system.
It is possible to configure every detail from" the number of the stars" to "if the stars can represent decimals or not".
There is also an option to display small or big stars and images can be changed with any other file easily.
Although the plugin can be used with any scripting language, a PHP file that handles the requests is already included in the download package.
