QUOTE:
Sure.. In your code, check if you are on an article page. To do this you test for the URL parameters "option" and "task". The parameter "option" should be set to "com_content" and "task" should be "view". eg:

if (mosGetParam($_REQUEST, 'option') == 'com_content' && mosGetParam($_REQUEST, 'task') == 'view') {

// put your code in here.. 

}
