Hey!  Scrotshot is really great! 
I am downloading your openbox iso right now.  Eager to check it out.

I was wondering how can i configure scrotshot to open a different viewer after taking a screenshot?  Like viewnoir or gthumb?

Thanks a milion and great work!

EDIT:   I looked deeper and found a solution.

I just changed
display_screenshot="yad --title=\"Screenshot Preview\" --picture --size=fit --window-icon=camera --filename=\$f --width=800 --height=600 --center --inc=256 --timeout=30"
to
display_screenshot='viewnior $f'
in
scrotselect and scrotshot
located in
/usr/local/bin/

Again...thanks a million this is a great tool!
