// JavaScript choosepics.js - home banner image rotation

//How to add images to the home banner:  There are three columns: left, middle, right.  Each function below (chooseLeftPic, choodeMiddlePic and chooseRightPic) corresponds to each column and chooses a picture randomly that is assigned to that column. Put Guggenheim pics in Left Column. 
//To add an image, put the actual image in /image/homerotate/ folder - image needs to be 325x225.  
//Go to function for the column you want to put it in and copy the last "case" line.  Change the case number and the path to image, text that will appear below the image, link to where image goes, and alttext.  If you do not want to include text or link, you can leave it blank like this "".  Change the "numImages" number at the top to one more than the last case number.  
//To delete an image, comment out the line containing the image using /* */ and change the number of the case for the images that come after that one, and change the "numImages" number at the top. (this way you have a record of what you have used already). //
