How is it that many of the img files of different cities are the same size. Nine of them are 22,589 kb and 25 of them are 23,560 kb. In fact Poznan is 23,560 when in a previous post it was only 12,016 and Kiev is 23,560 when previously it was 16,458. I have not tried any of the ones in this post yet but the previous ones worked. I guess I'm just curious as to why the size differences. Has anybody tried any of these new ones?
