/*
based on openLarger() from http://www.gelighting.com/na/scripts/global.js

Usage example --- onclick event (also applies for href="javascript:..."):

	<a target="_blank" href="images/foo.jpg"
		onclick="openNakedImagePopup('images/foo.jpg', 640, 480, 'GE Profile(TM) Washers and Dryers'); return false;">
			view larger photo
	</a>

	Got &, <, >, ', ", or other special characters?

	<a target="_blank" href="images/foo.jpg?foo=1&amp;bar=2"
		onclick="openNakedImagePopup('images/foo.jpg?foo=1&amp;bar=2', 640, 480, 'GE Profile&trade; Washers &amp; Dryers'); return false;">
			view larger photo
	</a>

	REMEMBER:
	While this function runs encodeEntities on the imageURL and altText,
	you still need to escape <, >, &, ', and " characters in onclick events
	or any other HTML attribute value (the browser unescapes them, then
	openNakedImagePopup re-escapes them).
	While most browsers are lenient, XHTML validation tools will issue
	warnings or error messages if you do not do this.

Usage example --- <script> element (also applies for .js files):

	<script type="text/javascript">
		function openPopup () {
			openNakedImagePopup('images/foo.jpg', 640, 480, 'GE Profile(TM) Washers and Dryers');
			// Got special characters?
			openNakedImagePopup('images/foo.jpg?foo=1&bar=2', 640, 480, 'GE Profile\u2122 Washers & Dryers'); // [1] one way
			openNakedImagePopup('images/foo.jpg?foo=1&bar=2', 640, 480, 'GE Profile&trade; Washers &amp; Dryers', true); // [2] another way
			// notice lack of entity escaping here --^ in the URLs.
			// you don't need to entity-escape the URLs in <script>
			// elements or .js files.
		}
	</script>
	<a target="_blank" href="images/foo.jpg" onclick="openPopup(); return false;">
		view larger photo
	</a>

	Got &, <, >, ', ", or other special characters?

	REMEMBER:
	Since browsers do NOT unescape entities in <script> elements like they
	do in HTML attribute values, you do NOT need to do HTML entity escaping
	here.  \ escaping still applies.  See [1] above.

	If you don't like looking up Unicode hex values, you can use HTML
	entity escaping instead.  However, within <script> elements and .js
	files, you MUST pass an optional fifth argument of true.  In other
	contexts, such as onclick attributes and javascript: hrefs, you
	MUST NOT pass the optional fifth argument.  (The browser unescapes
	entities in onclick/href attributes, but not in script elements or
	.js files; the optional fifth argument tells openNakedImagePopup
	to *not* perform entity-escaping on the alt text.)
