Scroll down by inside dragging not by slider possible ?

[pstein]

Assume I have a big picture which is shown in original size in XnView.
Because it is so big large parts are only visible when I drag the sliders
on the right side and at the bottom.

However I have seen some other smarter ways of "scrolling" in other
image viewers:

I click with the left mouse inside the picture - hold the mouse key down
and drag the whole picture up to the desired direction.

Is this possible in XnView as well ?

Which setting do I have to enable to have a scrolling option in this way ?

Yes. Check or change the setting in Options>View>Keyboard/Mouse for 'Move picture'. It should be on either Left or Right Button.
=> you can also directly try Right (or Left) Mouse Button and move the image.
