Like many others, I have noticed that Facebook increased its photo size from 604 to 720 pixels. At the same time, I noticed that the commands in my last post weren’t perfect. I have tried to write an improved script:

• facebook.sh

Simply run it in your photos folder and it will make a ‘facebook’ directory to which it copies your processed photos. By default, it only handles the photos in the current directory. To make it recursive (it will skip the ‘facebook’ dir), just remove or edit “-maxdepth 1″.

As before, I can recommend ImageMagick and Cygwin if you are a Windows user.

Shouldn’t have to mention it, but: Use at your own risk.

A few tips for using Facebook and/or other services. You will need ImageMagick and linux or Cygwin.

Order images correctly

Copying images to your computer, or rotating them, may ruin the files’ time (of last modification). If your album contains images from several cameras, the file names can’t be used to sort the images either. The following command renames the files to the second they were taken (see Exif).

c=0;for i in *.jpg;do t=`identify -verbose $i |egrep 'Exif:DateTime:'|sed 's/[^0-9]//g'`; mv $i "$t-$c.jpg";c=$[ $c + 1 ];echo $i;done

Remove excess information

Be sure you don’t share more than you mean to! Also, saves you a couple of bytes to upload. (Copy files to a new folder first.)

for i in *.jpg;do mogrify -strip -resize 604x604 $i;echo $i;done

Of course, for some services, keeping the metadata could be useful.

Anonymize file names

Finally, you may want to rename the album file names:

c=0;for i in *.jpg;do f=`printf "%04u" "$c"`;mv $i $f.jpg;c=$[ $c + 1 ];done
