I can't believe I am the first to comment on this great little plugin (actually it's 2 plugins - you'll need both of them by the way....).I tried this because I needed to insert an Alexa Rank graph & other custom scripts, and was having problems with other similar extensions (which are top rated)... This worked straight away without any problems & is just so easy to use it's unbelievable!!!.... Just remember to use Tiny MCE editor (it doesn't seem to like JCE...) plus follow the instructions regarding setting up permissions in articles as explained on download page (instructions are easy enough even for newbies to follow)and you're set to go. Thanks so much for sharing this great tool with Joomla community - Highly recommended.
