The template I made in Photoshop has a picture size of 555 x 390, which is hardly much better than the posted image of 400x281 (which I use, so pictures fit well into the 2 column mode of the earlier posts).
I will certainly not create a bigger template, because it was really a shitload of work to get this one done. And since the screens itself have alot of the environment in it, it won't be much more details visible (beside the environment around us, which is most likely as interesting as if a sack of rice in china topples over...).
So no, there are no bigger screenies than the one of the frontpage
