How to resize

Now you can get images, but most of them are too large.
It is not good upload image as this size.
Shrinking needed.

What if you have dozens of image to shrink,
open image editor and scale down and save.

Linux has "convert" command line image tool
Shell script will help automatic image resizing.

convert tool option

convert between image formats
as well as resize an image, blur, crop,
despeckle, dither, draw on, flip, join,
re-sample, and much more

There are so many options, here let me say about resizing.

Set example.png width 1000 and save to example2.png
Height will be set with rate of example.png.

$ convert -resize 1000 example.png example2.png

Set example.png size 50%, save to example2.png

$ convert -resize 50% example.png example2.png

Example of shell script :

Images in ./travel will be converted to ./travel2
(travel2 folder must be created before)

#!/bin/bash
FILES=./travel/*
for f in $FILES
do
  fname=`basename $f`
  cmd="convert -resize 50% $f ./travel2/$fname"
  echo $cmd
  eval $cmd
done

You can easily modify the shell script as you want.
