So, I enjoy going through the archive here on Pinside every now and then looking up details on various machines, but one thing that really bugs me is the image viewer: It completely lacks the ability to zoom in and out so some images turn out to be uncomfortably small to look at, while others are so big I can't see more than a piece of them at a time.

My feature request is that zoom be added to the image viewer in the gallery so that images can be zoomed in and out, reset to their original size, or fit to the current browser window. :B
