I’m not sure about a slide show per se, Peter, and I suspect you’d have to use something besides DxO to create one. If you could get them in a slide show there are ways of converting it to a short video clip and you can upload that, I believe. If not, I’ve done one that I uploaded to youtube (had to create a free account) and then linked to it.
@Peter_Morrissey , I’ve used a program called “Irfanview” to create a slide show of several images as a single file. It is free and works pretty well. I’m sure there are a lot of others. You can set the timing of how fast the slides are shown too, though I don’t know what all speeds are available. But it is nice to have a single file that can be downloaded and then just clicked on and the show runs.
