OpenX supports two storage types for banners: SQL storage and webserver.

- SQL banners are located in the database itself

- Webserver banners are located in folder on the server's file system

The question is what storage to use for your OpenX installation, SQL or Webserver banners?

We suggest using web server to keep and deliver your banners because it will work much faster. SQL storage OpenX banners take up space in the database and make it slower and somehow overbloated.
