// to add or remove images from the PicTextArray list beloe:
//	1. copy/paste the last line to the end (make sure to place it inside the closing paren)
//  2. add a comma at the end of the last line you just copied (will now be the second to last line in the list)
//  3. change the first value to the relative location of the new picture being added
//  4. change the second value to the name of the picture (1st caption line)
//  5. change the third value to the name of the university (2nd camption line)
//
//  for example:
//	...
//	new Array("images/frame_UA.jpg", "Denny Chimes", "The University of Alabama"),
//	new Array("images/frame_pic3.jpg", "Test Name 3", "Some University 3"), <------ don't forget to add a comma
//	new Array("images/newimagename.jpg", "New Caption", "New Univeristy Name") <---- update the new line values as listed in steps 3, 4, & 5 above
//  );  <---- be sure the new line is added above the closing paren
//  ...
