I am currently displaying all the articles based on search results and certain business conditions in a VF page. When displaying the articlelist i am using <knowledge:articleList> which is all working fine but i also need to display the article rating and View count for which I am currently querying on KnowledgeArticleVoteStat and KnowledgeArticleViewStat to get the count.
The problem is i am getting the count as integer from this query and need to convert this integer number into a image with the star options as displayed in the standard article page. I also tried articletoolbar option but it works only for article detail page, but i need this in the list view of articles. I just need to convert the integer count to standard sfdc article rating image, can any point me whats the best approach for this?

I don't have Knowledge available in my org but I suspect the ratings look like star icons on bottom of http://blogforce9dev-developer-edition.ap1.force.com/salesforceicons ?
If that's the case you can simply take
<img src="/img/samples/stars_300.gif" />and convert it to<img src="/img/samples/stars_{!article.KnowledgeArticleVoteStat}00.gif" />.I have no idea if range of this int is 0 to 5, sorry. if it can be bigger - just play with scaling it down to thresholds as you see fit, for example
{!MIN(5, CEILING(article.KnowledgeArticleVoteStat / 50))}(here's the reference for math functions you can use). Whatever logic you might decide is needed & which you can express in formula fields syntax that will end up being a 0-5 number.P.S. There are some questions here that warn us that directory structure, filenames etc aren't a "supported API" so Salesforce can change them anytime and then your customization breaks. To play it safe you might decide to upload these images as your own static resource.
