// Insert Random Top Image

// There should be no gaps between number of images in rotation
// For example... 1, 2, 3, 4, 5... not 1, 2, 4, 5, 8, 11... etc.

// ___ Get Random Number

// For number of images, change the '.random()*4)' number
// The number should be 1 less than actual # of images
// For example
// 5 images reads: (Math.round((Math.random()*4)+1))
// 10 images reads: (Math.round((Math.random()*11)+1))

random_num = (Math.round((Math.random()*4)+1))

// ___ Write

// This is the code to write into the document
// Any text or html should be in quotations "<img..."
// Random number variable does not need quotations
// Images are set to follow "image_1.jpg" format

document.write("<img src=insert/insert_" + random_num + ".jpg>");
