Had to answer this one!
The wind can come from any direction, you can get a crosswind anywhere in the world!
Runways are normally roughly alligned into the prevailing wind, but on any given day chances are there will be a crosswind. Sometimes that will be particularly strong, as it appears above.
Each aircraft type has a crosswind limit, and pilots will have varying crosswind limits in which they can operate.
Looks like if this 747 did touch down halfway along the runway, the crew let things run away with them on this occasion. Yes a 747 can stop in 5000 without much difficulty, I've landed on a BA 747-400 at Boston on a runway just over 7000' long and we didn't use more than 2/3 of it.

Just to add what Crosswind mentionned, designers try to ensure runways are roughly aligned with the prevailing wind.
However, often envrionmental of physical factors prevent runways from being built into the prevailing wind. Factors such as water, obstacles, noise sensitive areas, etc etc. When this happens, you may find that these types of runways are more succeptable to crosswinds.
But winds being what they are, it's a very inexact science!
