/*
To Add A New Page:

General:
1. Open a current file and "save as" another name (the name should be abbreviated like: feat_fh.html"
2. All images should be jpgs and begin with the same name as the page and end with "_" and the image number (e.g., feat_fh_1.jpg)

In this Javascript File:
3. Update end of variable "imgs" with a new entry:
	an apostrophe, the filename (minus the .html), a pipe ("|"), the total number of images, and another apostrophe (e.g., 'feat_fh|4')
4. Add a new caption array variable with the name "caption_" and the filename (minus the .html), (e.g., caption_feat_fh)
5. Update the new caption array with the new captions (follow how it's done below)
6. Update the function "GetCaptionArray()" with 3 new lines as follows:
	case "feat_fh":
	  return caption_feat_fh;
	  break 

In the new html file:
7. Update the "randomImages" reference in the onload function in the body tag with the number that represents the new item's
	 index in the "imgs" array (note, the count starts with 0). (e.g., randomImages(9))
