Conveyor Belt slideshow - randomized

Conveyor Belt slideshow script

http://www.dynamicdrive.com/dynamici...rightslide.htm

I love this script but I want the images randomized so that each time a user comes to the site they don't see the same first 3 photos before moving on to other sections.

Thanks.

An excellent array randomizer was written by Mike (mwinter) from these forums. It is still available here. What you do is place the unit after the array, in this case the 'leftrightslide' array. A good place would be just after this line in the Conveyor Belt slideshow script:

Then after the unit put this:

leftrightslide.shuffle()

Then each time the page loads, a random order will be assigned to the array and thus the order of the images shown.

Nice! That was a snap to implement.

The whole unit is now running great in a core phpnuke block. Randomized now too

Thanks!

anyone got a way to continuously randomize the slides? and also to make sure slides dont repeat?

i got something... not completely continuous, but it gets the job done...
