	fi

echo "$unused_count unused images found. See find-unused_images.log for found list."
echo ''

the script hung for me when grep'ing so I simplified it a bit:

#!/bin/bash

# Escape code
esc=`echo -en "\033"`

# Set colors
cc_red="${esc}[0;31m"
cc_green="${esc}[0;32m"
cc_yellow="${esc}[0;33m"
cc_blue="${esc}[0;34m"
cc_normal=`echo -en "${esc}[m\017"`

files=(`find . -type f  \( ! -path './backup/*' ! -path './External/*' -and \( -name '*.xib' -or -name '*.[mh]' -or -name '*.storyboard' -or -name '*.mm' -or -name '*.html' -or -name '*.css' -or -name '*.js' -or -name '*.plist' \) \) -exec echo ''{}'' \;`)

images=(`find . -type f \( ! -path './backup/*' ! -path './External/*' -and \( -name '*.png' -or -name '*.jpg' -or -name '*.jpeg' \) \) -exec echo ''{}'' \;`)
image_count=${#images[@]}

i=0
unused_count=0

echo 'Unused file list:' > ./find-unused_images.log

for image in ${images[*]} 
do
	let "i += 1"

	name=`basename -s .png $image`
	name=`basename -s .jpg $name`
	name=`basename -s .jpeg $name`
	name=`basename -s @2x $name`

        echo searching for $name
        grep -Rl $name
        echo
        echo
done

Given the output you can do a regex search for \n.*\n to find unused images (unused images will just have "searching for name" outputted with empty space before and after)
