/*
You would use this script to pop open a new window (of a specific size) to display a HTML page or graphic.

Paste this line of code around what you want to serve as your popup link.  Be sure to customize the url, name, and window properties.

<A HREF="javascript:new_window('url','name','window_properties')"></A>

Explanation of new_window attributes:
*URL (required) - The location of what you want to display (i.e. "../misc/somefile.html")
*Name (required) - This is the name you give the window (useful when you want to refer to the window later).
*Window Properties (required) - A string containing a comma-separated list determining whether or not to create various standard window features.
	Below are some explanations of the more important window properties
		-Height (required) - Specifies the height of the window in pixels.
		-Width (required) - Specifies the width of the window in pixels.
		-Toolbar - If yes, creates the standard browser toolbar, with buttons such as Back and Forward.	
		-Scrollbars - If yes, creates horizontal and vertical scrollbars when the Document grows larger than the window dimensions.
		-Resizable - If yes, allows a user to resize the window.
	Note: If a window property is not included, it's assumed to be "no" or "0"

Example:
<A HREF="javascript:new_window('../images/slide_modems.jpg','slide','height=457,width=588,left=0,top=0,scrollbars=no,resizable=yes')">Modems</A>
*/

function new_window(url,name,window_properties) {
