Free extensions for Joomla!

Sorry if this may sound stupid, but how the heck do I install a plugin/extension in Xmap? Xmap is working fine but now I am trying to install the EasyBlog Xmap Plugin: http://stackideas.com/docs/easyblog/plugins/xmap-plugin.html

I read the guides but either I am completely blind (that wouldn't be the first time!) or the extension tab install option in Xmap is missing.

I am doing the following:
Administration > Components > Xmap (now I have TWO tabs): Sitemap & Extensions

If I click on Extensions, it actually takes me to the normal Joomla extension manager. So no install option. And if I try to install the plugin using the normal site manager, it will throw an error message since it needs to go through Xmap.

I am using Joomla 2.5.9 and Xmap 2.3.3 (I was on 2.3.2 but upgraded to the beta since I thought that might solve the missing Extension Installer problem).

Any ideas?

xmap plugins will install from normal Joomla extension manager. if your plugin do not install , it is may not compatiable with joomla new version.

Thanks, I have solved my problem. I have indeed used a wrong plugin package for an older version of Joomla. As soon as I took the correct one it worked like a charm.
