Why is vertical scrolling (seemingly) faster than horizontal scrolling? [Details inside].
Whenever I have a (very) big photo in my browser lets say, a photo that is twice as big as my screen and I use the scroll function I find that vertical scrolling goes fst, yet horizontal scrolling goes s l o w.
What is the reason why this occurs?
