====== Configuration Setting: fetchsize ======

Maximum size (bytes) fetch.php may download from extern. This is used to cache external images and resize them if needed. To disable this functionality completely just set this option to 0.

  * Type: Number
  * Default: ''0''

Enabling this option is two-fold:

  * positive:
    * it allows for nicely resized external images
    * external servers won't be hammered (local caching instead of hotlinking)
  * negative
    * this could be used for denial of service attacks (A small request causes the server to download much bigger data)

It is recommended to enable the option with smaller (common image) sizes, like 100 to 150kb.
