/**
 * Stats is a Gallery mod that allows photo statistics to be displayed.
 * Use the url variable "type" to select the statistic to display.
 *
 *   - number of views (clicks) - use stats.php?type=views
 *   - upload date - use stats.php?type=date
 *   - number of votes (stats votes) - use stats.php?type=votes
 *   - ratings (Gallery votes) - use stats.php?type=ratings
 *   - capture date - use stats.php?type=cdate
 *   - latest comments - use stats.php?type=comments
 *   - random images - use stats.php?type=random
 *
 * The photos displayed can be restricted by their upload date.
 * Use stats.php?type=date&period=<x> where x is the number of months
 * that you want to display. For example:
 *   stats.php?type=date&period=0 displays all photos uploaded during
 *	   the current month.
 *   stats.php?type=views?period=1 displays the number of views (clicks)
 *	   for all photos uploaded during the last month and the current month
 *	   stats.php?type=date&period=6 covers the last 6 months.
 *
 * The images listed can be restricted to one album by using the album
 * parameter. For example:
 *   stats.php?type=date&album=new displays only images from the new album.
 *
