Image posting module (aka #post)
This module is set to automatically post images every 15 minutes. To be precise, after 15 minutes pass since the last image was posted by this module, it will start checking if 50 chat messages have been posted since the previous image was posted. Then, the module will wait 30 seconds since the last chat message to post the next image. This last interval is added to avoid interrupting a discussion with the large image.
