/*
	Instructions for adding to the random photo.
	
	Step 1: List all the photos to be selected from in the parentheses of photo_array = new Array(...). 
			List the filename of the photos without path but make sure to include the extension.
			Enclose the filename in double-quotation mark and separate the filename with commas.
			
	Step 2:	Make sure the number of (0)zeros in the string assigned to display_list is equal to
			the number of photos listed in photo_array.
			
	Step 3:	Make sure the graphic files listed in photo_array is in the "h_images" folder from
			the root.
	
	Step 4:	That's it.  The rest of the code will handle everything else.
