For example...

Step One
- Download 'infopop_vb.zip' and extract its contents to an easy to remember folder.

Step Two
- From within the Control Panel, go to Styles -> Download/Upload. Under Upload Existing Style Set, click browse and select 'infopop_vb.style' from the folder you extracted the archive. Select 'No, create a new style' for Overwrite style existing style. Upload File.

Step Three
- Via FTP, upload the 'infopop' images folder and all its contents to your vB images directory. (ex: /forums/images/infopop)
