I recently put up a page (www.intertechcable.com) that has a random image generator when the nav buttons are moused over. I'm relatively knew to javascripting, but was able to band aid some code together that, while large in file size, is doing the job. The customer has no concerns about the file size which is rather large, but when a new window is opened the javascript tries to reload the images generating a ton of hits and bandwidth.

Any suggestions would be greatly appreciated as I can anticipate our server getting a little picky about this bandwidth hog.
