hmm looking at feedjit they now have registration and some parameters in the code that many users probably wont be able to find on their own. Instead of releasing a plugin that might be hard to configure (no easy way to find the parameters used except looking at the javascrtip code) I'll post here a step by step how to make your own.
1) create a new folder in /plugins/Feedjit
2) in this new /plugins/Feedjit/ directory create a new file called global_start.php with the following contents
PHP:
$TMPL['feedjit'] = '
<script type="text/javascript" src="http://feedjit.com/serve/?vv=955&tft=3&dd=0&wid=3f1a72ecca23014b&pid=0&proid=0&bc=FFFFFF&tc=000000&brd1=012B6B&lnk=135D9E&hc=FFFFFF&hfc=2853A8&btn=C99700&ww=200&wne=10&wh=Live+Traffic+Feed&hl=0&hlnks=0&hfce=0&srefs=0&hbars=0"></script><noscript><a href="http://feedjit.com/">Feedjit Live Blog Stats</a></noscript>
';
Replace my javascript code above with your own generated from
http://feedjit.com (note the javascript above is between 2 single quotes)
3) copy the other files required for a plugin. info.php, empty index.html, and /languages/ folder with at least english.php even if its empty.
So your directory structure shoudl look like this:
plugins/Feedjit/
--index.html
--info.php
--global_start.php
--languages
----english.php
4) From your admin panel edit wrapper.html and paste {$feedjit} where you want the widget to show up
Congrats! You made a plugin
If you have any questions, let me know.
