The Dragon Reborn cover and a lot of others is actually a really nice picture, but it isn't at all related to WoT. I mean, it has an ACTUAL DRAGON ON IT. And there are some even worse ones than that. 

Well, yeah, but I wouldn't say that they're ugly.

I actually quite enjoy the US covers... EotW is probably my favorite. The eBook cover for The Shadow Rising is really awesome.

And I'm not sure why people think the French covers are terrible. I like The Dragon Reborn one especially. (Sure, it looks like it is about eight centuries, old, but still.) The Eye of the World one, though... :/
