# YAEG(Yet Another Easy Gallery) v.1.5 by Markku Virtanen (Cahva^RNO)
# Thumbnail function is taken from php.net by unknown person
# Email: cahva@po-rno.fi)
# www: http://www.po-rno.fi or http://rno.wmhost.com
#
# Created: 2003-11-19
# Updated: 2004-04-22
# This script is meant to be as easy as possible. Works with GIF,JPG and PNG pictures.
# Gallery viewers can also comment the pictures too with this! Aint that neat! :)
#
# Usage
# ------
# Only things you have to do is:
# 1.Create directory
# 2.Set the permission to write to directory
# 3.Copy pictures to directory
#
# Thats it. Gallery is now ready for use. Open a browser. Go to the directory you created.
# For the first time it makes the thumbnails so it takes a bit longer than usual.
# You can later copy pictures as you want. It allways makes thumbnails for new pictures.
#
# Changes:
# v1.5 - added possibility to use other directory than the one where this script is(see $dirsetting)
