XnView Software

In viewer mode setting auto image size as "fit image to window width" to better view the picture , if there's a vertical scroll bar then PAGEDOWN should means scroll to the below part of this picture in PDF reader while in XnView PAGEDOWN will go to the next picture ,
could you change this viewer ...

Yes, a batch process in Export is really needed. Could the author please add this function in "batch convert"? Or how can i use script to batch convert color JPEG files to black-and-white TIFF?
Thanks a lot!
