# Description: Creates GIF thumbnails of bigger size x pixels
# Works for both gif and jpeg pictures
# This scripts needs many local programs to work: jpegsize,
# djpeg, pnmscale, ppmtogif, ppmquant, gifrsize, convert
# The path to these programs are stored in the config_XXX.php
# Creator: T.Baron
#
# INPUT: $1->Path to picture file
# $2->Path to resulting thumbnail
# $3->largest size (in pixels)
#
# OUTPUT: thumbnail file at $2
