Template:Scrolling map

 For displaying large side-scrolling maps in a useful fashion.

Parameters
There is also an optional parameter: imagewidth to modify the size of the image itself, rather than the boundaries of the scrollbox.
 * 1) Image name (don't include the "Image:")
 * 2) Height constraint (in pixels, without the "px") — optional
 * 3) Width constraint (in pixels, without the "px") — optional

If width/height aren't specified, the image will expand to either its full width/height, or the width of the page (whichever comes first). Height can't be constrained by the page.
