XnView Software

Reload image(-es) when xnview window gets focus. (gsview has this function)
This is very useful feature for viewing images that are automatically created. And this can be controlled through the option

Just came here to post the same suggestion:

An option for XnView to check the timestamp to the currently shown image.
If the timestamp has changed since the image was last read, XnView should prompt the user whether he/she wants to reload the image.
An additional option should be available that would simply reload the image if the timestamp has changed without a prompt.

For people like me that use command line tools to iterate over some image process, this would be very useful and effective.

FWIW, Notepad++ has such a feature for text files and it is very useful.

*bump*

I still think this would be a very useful feature. XnView would install a file change callback to be notified when the image file has been changed.
Then it would trigger a reload.
