The UL warning image displayed during shutdown can be modified by replacing the file
/usr/share/boot-anim/ul_warning.565
with an appropriate alternative, in 1200x900 "565" format.
For example, you might wish to try: modified-shutdown.565.
On a linux system, you can convert 1200x900 PNG images to 565-format images as follows:
$ yum -y install netpbm-progs $ pngtopnm myfile.png | ./ppmto565.py -z -o myfile.565
