How to Install 99% of Drupal Modules:
Download the module from http://drupal.org/project/Modules and extract it.
FTP to your Drupal site. Drop the extracted module folder into the sites/all/modules folder (if that directory is not there then create it).
Using your browser, visit www.yourDrupalsite.com/user and log in.
Now visit www.yourDrupalsite.com/admin/build/modules/.
If you forget this URL, just go to the admin page and click the Modules link.
Select the checkbox next to the module that you just installed. If needed, also tic any sub-modules that you just installed.
Click on the Save Configuration button.
In a couple of seconds, the newly selected module will install itself. Any errors will appear in red.
Go to www.yourDrupalsite.com/admin/user/permissions and set the permissions for that module so that different roles can use or administer the new functionality that the module has added (not required for all modules).
Go to www.yourDrupalsite.com/admin and you’ll see links to customize the settings of your newly installed module.
