// get_Image() Function
//
// Chooses a random image to display from preexisting set of images in an array
// - the image will NOT be forced to a specific size
// - border size of zero means that no ugly border gets drawn around your image when displayed
// - debugging enables or disaples some debugging messages -- useful for making sure the right base url path is set
// - imgBaseURL is the absolute path to where available pix for random selection are located, must include trailing slash
// - adding a new image is simple, add a new entry to the array -- done!
// - don't forget to turn of debugging when going to production server
//
// USAGE:
//
// Be sure to load this script library in your document
//
//
//
// When calling the get_Image function in the page body, use the following code...
//
//
//
// ...this will load a random image from the below defined array into your document
//
// Also, make sure you update the imgBaseURL variable to be the path to your image
// image directory base, it must end with the trailing slash to work properly.
//
