A slightly less random "random order"

The slideshow "use random order" option displays images randomly (as it says). However, I find that sometimes it feels like it's being repetitive, or getting "stuck" showing a few images more often than others. I know that's possible with random selection, but sometimes I'd like a little less randomness :)

Is it, or would it be, possible to set a slideshow up to display each image in turn, in a random order without repeats, then shuffle and start again? Something like dealing a deck of cards. That way, I'd get each image once before repeats. (I've seen some programs which offer an intermediate level, randomize a group of N images and show them before getting another random set - this is a little more random, but still avoids too much repetition. It's probably overkill, though).

Also, when building an EXE slideshow, is the order set at creation time? I didn't see anything about command line parameters for the EXE, but is it possible to select sequential or random at runtime?

Thanks,
Paul.

Strange, it's not really a random order, each picture must be showed only 1 time.

No sorry no option

Is it possible to have the photos played in a different random sequence each time, or at least not start with the same photo?

This is available in another viewer, but I like XnView's transition effects much better.

Well, think of it like dealing a deck of cards. Shuffle the deck, deal each card once. After finisning, reshuffle and deal again.

I can get almost this effect by randomly shuffling the list of pictures, but then it doesn't get reshuffled after each pass through the "deck".

Sorry, I'm not sure I follow. Yes, that's how it should be coded. What I'm asking is, is it available in XnView, and if not, is it a reasonable request for a new feature?

Hello Paul,

I was hoping that the two links in my previous post would back up your explanations and provide Pierre with ideas for an improved “randomness”, because the articles are written from a developer's point of view.
