//choose a photo at random for the technology classrooms page
//from the technologyclassroom_photos folder

//if you delete photos from the folder, you must renumber
//the images so they are numbered consecutively from 1 up

//if you add photos, they must be named like this: 1.jpg, 2.jpg, 3.jpg, etc.
//if there are seven photos in the folder and you add a new one, you must
//name it 8.jpg and change the variable "maxphoto" in this script to 8.

//VERY IMPORTANT: The variable "maxphoto" must equal the number of photos
//in the technologyclassroom_photos folder. If this variable is larger than
//the number of photos, sometimes no photo will load. If this variable is
//smaller, the higher-numbered photos will never be chosen.
