It renames files from directories as last directory + increasing number on every folder the index is reset
#/usr/bin/bash
path=
i=0
prevname=
for file in */*/*/*.jpg; do
path="${file%/*}"
name=`basename "$path"`
if [ "$name" == "$prevname" ]; then
i=`expr $i + 1`

Extract images from pdf but, surprise! The images that contain alpha channels are extracted as two images. The source and the mask, as they are stored inside pdf file. This script recombine them into an one png file with given transparency
#/usr/bin/bash
# extract images from pdf at first-hand
#prefix=pict
#echo extract images from "$1"
#pdfimages -j "$1" $prefix
# IMAGES ARE SAVED SECVENTIALLY AS IMAGE AND THE NEXT IS A MASK IMAGE !!!!
declare -a files=($(ls *.ppm *.pbm))
mask=
image=
for (( i = 0; i < ${#files[*]}; i = i + 2 ))

Insert lines into certain files. After first and before last line
#!/bin/bash
# insert text lines after first line and before last line of file
# $1 = a glob expression like */assets/*.css
# $2 = a literal to be inserted after first line
# $3 = same as above but inserted before last line
for f in $1; do
eval "sed -ri '1 s/(.*)/\1\n$2; $ s/(.*)/$3\n\1/' \"$f\""

Extract a range o pages $2 - $3 from a PDF document $1 as PNG images prefixed with $4 - for quality the script saves images with high resolution and scales them down
#!/bin/bash
tempdf=$(tempfile)
gs -sDEVICE=pdfwrite -dNOPAUSE -dBATCH -dSAFER -dFirstPage=$2 -dLastPage=$3 -sOutputFile=$tempdf $1
gs -dNOPAUSE -sDEVICE=png16m -r600 -dDownScaleFactor=3 -dBATCH -dSAFER -sOutputFile="$4-$2-%00d.png" $tempdf
rm -f $tempdf
