Screensaver size limit?
I have a little over 23,000 image files. I built a simple slideshow screensaver on the Mac (OS X 10.15.4) and it works fine, although it complained about the size of the resulting screensaver after the build (~6GB). When I tried to use my original files iScreensaver crashed (crash dump on request), although these were unmodified files size-wise. So I resized all of my photos to max 1024x768 and adjusted JPEG compression to 80% which seemed to work.
When I moved over to the PC (Windows 10 Pro version 1909) and tried to build, the build finished with errors, complaining again about the resulting screensaver size and said there was a size limit of 4GB. That sounds suspiciously like a 32-bit limitation. I really don't want to cut my image size down further and I'm not going to limit the number of images (in fact, that may grow). I'm not sure using a tighter JPEG compression will help much either. I'd really like to build on the PC for the Mac since the PC is where all of my images reside.
Is there any way to get iScreensaver to fetch, resize, and display images from a local folder (with subfolders) rather than producing a gigantic executable? Thanks for any guidance you can provide.
