Bug fix 2012/vik/try.sh

The additional commands I added cannot come first because the program
(as the bugs.md states and now more clearly) will likely crash (and does
in all the systems I tested) if the file does not exist. This did not
show itself the first time because the files already existed but running
make clobber before the script would remove the image files and thus a
crash (or actually two) would occur the first time the script was run
(second time it would be fine as the files it uses then exist).
