Rotating advertising images

[mikescott]

I have 24 ad sponsor images. I want 6 to appear on a page at any one time in a vettical column one under the other. One each page refresh/mouse click I want to rotate through all 24 images so that - over time - each one is diplayed the same number of times, and each one appears in each of the 6 positions.

I can sort of do that using:

<cfparam name="SponsorSwap" default="#randrange(1,24)#">

then:

<cfif SponsorSwap is "1"> image1, image2, image3, image4, image5, image6</cfif>

<cfif SponsorSwap is "2">image2, image3, image4, image5, image6, image1<cfif>

and so on...

But that is a lot of code.

Is there a better way to do this?

Thank you

Store the last displayed timestamp.  Then get the 6 that have waited the longest.
