Using a queue is part of GCD. You should probably not use the main queue since
that is analogous to the main thread and the main thread is meant for updating
the UI.
The good thing here is that you can sort of preload the next image in a queue
after your last one has displayed.

Sure. Just be aware that if you're using NSImage, simply loading an NSImage
does not rasterize

What if you spawned another process (NSTask?) from the screensaver and tested
if a timer works in that? It’s hokey as hell, but I use this approach to
monitor a running process and do things when its state changes to suspended.
See if you can fire off a process and have a timer in it that logs

I have kind of a slide-show app.
Sometimes, when it switches from one image to the next, there is a noticeable
lag when the file size of the next image is very big, say, 50 MB or more.
