Hello, this is a question that's been asked many times before but in fragments due to people usually knowing how to get started...  Can we assume NO knowledge on my part as to how to do this? Okay, here goes:

How do I get images to display randomly on a page each time it reloads?
i.e. A page banner that is different each time it is visited.  (I don't want the image to change whilst actually on screen).

I know I need a combination of Javascript and HTML but that's all I know.  Could somebody supply all the necessary code and end this question forever?

Many thanks indeed.

It is simple and to the point.  I was going to copy it out, but it will be easier for you from the link

One other note about the link I posted, if you want to learn off of it it is very well documented
