$2 for a slideshow app? Sure, why not.
The user longing for FastStone would do well to look into XnViewMP, as would anyone wishing to play with lots of images but avoid LightRoom’s price tag and iPhoto’s weird interface and lack of features.
Being a huge fan of XnView, I came here looking for a slideshow app, since the Mac version strangely lacks the slideshow features of its superior and much older Windows counterpart. Sadly, the slideshow feature here is pretty minimal. You’ll need another app to move images between folders, there’s no clear way of selecting some but not others within a folder, and the slideshow offers no transitions or even cropping to fit the screen. The only nice feature here is the option to include every subfolder of the one chosen. You will still need to make a custom folder or set of folders just for this app unless you want to look at a lot of grey bars on the sides of your screen
Two bonus stars because the app basically works as advertised. One quarter point off, though, for no apparent options to rebind hotkeys. Friendly reminder that this is an accessibility feature.
