Add features to weboage

Hello I need add some information in a icecast admin page. Icecast admin pages are in xsl format, I just need modify one page, this one is the normal icecast page that I need modify [login to view URL] And this one is what I need. [login to view URL] As you see I just need add 2 columns and in that columns I need display the country name and flag of the IP in the row. This information could be taken from [login to view URL] . Also, I need in the same page, shown the same countries listed in a google map. Page should refresh each 15 senconds with the option to modify that time. I need use this page with more icecast ports so I just need copy/paste the same files in a new icecast folder and it should work without problem I will provide the icecast files to the work. That's it.
