Doesn't works very well.
Returns me an error

> Текстовый файл.sh: 7: arithmetic expression: expecting primary: " % (11 + 1) "

I am not very good with bash and i can't to seem to figure out what the problem is.
The line he is complaining on is
random_num=$(( $RANDOM % ($length + 1) ))

I think i found the application that does what i want, named Wally. (http://kde-apps.org/content/show.php/Wally?content=98455)

But i can't seem to get it change wallpapers, maybe i am doing something wrong?

You need to have Wally up and running to get it working. I started it as a command line, but didn't want to keep the terminal running, so I added it via alacarte (main menu).
