Joomla shows error of below pattern when trying to install a module or component.

Warning: is_dir(): Stat failed for /home/xyzabc/public_html/cms/media/install_443448a97a130/images (errno=13 – Permission denied) in /home/xyzabc/public_html/cms/administrator/includes/pcl/pclzip.lib.php on line 4287

This is because of 2 reasons

1 ) Bad folder permissions

2 ) Register globals in on in php.ini

The solution

1 ) Issue the below command after going to the installation directory of Joomla

# chmod 777 administrator/backups/ administrator/components/ administrator/modules/ administrator/templates/ cache/ components/ images/ images/banners/ images/stories/ language/ mambots/ mambots/content/ mambots/editors/ mambots/editors-xtd/ mambots/search/ media/ modules/ templates/

2 ) Copy the server’s php.ini to the Joomla installation directory and edit it to make sure that register globals is off. At times a httpd service restart would be required.

Hope now you can install components and modules to your Joomla installation.
