Screen Saver for use with my photos

I have a great screen saver that I have used for years - Firehand Screen Saver. Unfortunately now that I have come to install it on a new PC it won't recognise the ID and PW required. The guy who wrote and marketed it is no longer trading - the problem with one man businesses!

A remote hope - is anyone else using this screen saver (and its companion photo viewer Ember) and willing to pass on registration information
or
suggest a screen saver I can use with my photos. A search for free ones seems to just produce ones with built in images.

Thanks for the reply. I tried it and had a different problem. See my earlier post "Screen saver spreads image between the two monitors" a few hours ago.

Sorry - would have been easier had I known how to directly point to a post! What I had posted was

Although I have setup the two screens to work independently - one app running on one screen and a different app running on the other, when Windows screen saver kicks in, the image appears half on each screen. i.e. as if I was using a very wide monitor and the image is in the centre.
By contrast, the desktop images that I use as background, which are set to change every hour or so, display properly in their own screens. A different image on each screen.
What have I missed or is this a problem with the Windows screen saver?

When I got my old screen saver working, the problem went away so it was obviously a W10 screen saver issue.
