I dont have enough characters at the subject, so correcting here:
"Incorrect next picture sequence causes error in current/total image counter"
I'm on AMD64 Arch with XnViewMP 0.75.
An example:
I have 3469 pictures from a shorter video at 30fps, extracted with ffmpeg.
The current/total image counter shows an incorrect value, after the 100th pictures because:
The next one after 100 is the 1001th and not the 101th picture. Its common, after skipping the whole rage of 101-999, the sequence continues as "abc"->"abc"0...->"abc"9->"abd", rather than "abc"->"adb"->"abe"....etc.
I hope you can understand my logic

Thank you for time and effort!
