4chan dump script

any ideas on how i could improve this?

#!/bin/bash

# 4chan image dumper -- rimjob.sh -- ENTERPRISE QUALITY BASH SCRIPT
# last update: 16.02.2010 - Version 0.9.7
# direct cool stories, monnies, bug reports, etc. to blargh on #/g/tv - Rizon or blargh.macfag@googlemail.com
#
# improved rape.sh script (v5) => http://pastebin.com/f70ec1e29
#
# creates automagically new threads
# posts old thread URL into new thread and vice versa
# self tuning sleep timer to avoid flood
# uploads biggest files at first to avoid flood protection kicking in too early (default)
# to upload your shit sorted by name add -s as option
# http proxy support

# todo:
# fix those vars
# change flood retry function
# improve proxy function
# handle curl failures properly
# add some curl timeouts
# needs more colors

##### CHECK IF CURL IS AVAILABLE
CURL=`which curl`
if [ -z "$CURL" ]; then
    echo "This script depends on cURL, make sure it's installed and in your path."
    exit 1
fi
