The man page of xfce4-screenshooter mentions some of its options, including this one:

• -s (--save): Directory where the screenshot will be saved

To save to a fixed screenshot directory, go to Setting Manager -> Keyboard -> Application Shortcuts and click Add command. Add this command:

xfce4-screenshooter -s ~/screenshots

Assign it to any key you like, like PrtScr.

PNG is the only output format possible for now, but you could write a script that converts the screenshots automatically to JPG every time you take a screenshot:

#!/bin/bash

mkdir -p ~/screenshots

xfce4-screenshooter -fs ~/screenshots

cd ~/screenshots

mogrify -format jpg *.png

Save the script as shoot.sh and assign a shortcut key (CTRL+PrtScr works fine). The command to enter is sh shoot.sh. If you don't need the PNG files and you only want JPG files, you can add

rm *.png

to the script.

E-mail integration with Thunderbird:

#!/bin/bash

SCREENSHOTS=~/screenshots

mkdir -p $SCREENSHOTS

cd $SCREENSHOTS



xfce4-screenshooter -fs $SCREENSHOTS

SCREENSHOTPNG=`find . -type f -mmin -1`

SCREENSHOTPNG=`basename $SCREENSHOTPNG`

mogrify -format jpg $SCREENSHOTPNG

#uncomment the line below (remove the #) for even smaller files (and comment the line above):

#mogrify -resize 50% -format jpg $SCREENSHOTPNG

rm $SCREENSHOTPNG



SCREENSHOTJPG=`find . -type f -mmin -1`

SCREENSHOTJPG=`basename $SCREENSHOTJPG`

thunderbird --compose "attachment=$SCREENSHOTS/$SCREENSHOTJPG"

Thunderbird supports more default fields, see all parameters here.

Important
Mogrify is part of ImageMagick, so you need to have ImageMagick installed. On Ubuntu, you can install it with sudo apt-get install imagemagick
