Return Code

[rtlprmft]

Great tool. May i suggest to return 1 instead of 0 if feh returns because the next/previous/reloaded image was not found and keep 0 in case of user-quit ('q'). That helps to decide on the following action.

Remark: I am using it to display captured images in a loop in a bash script and want the user to decide if to capture another image or stop.
