ArtSaverApp 4+

Did you ever wish for a slideshow app that would show place and time of your images? or allow you to find the folder in which they are stored? or give you more control?

ArtSaverApp provides a "slide show" or "picture flow" for large image collections you have stored in a folder (or several folders) on your disk.
It is mostly geared towards people who want to see their images as large as possible, and with some information about each image currently being displayed.

With ArtSaverApp, you get more control than Apple's built-in screensaver: at runtime, you can review previous images (using arrow keys) and a few other controls; in the settings, you can control exactly which images should be displayed, duration, how it switches from one to the next, which information to display with the images, and more.
You can also download a companion (helper) app that allows you to turn ArtSaverApp into a surrogate screensaver (see the Manual or the web page).

There is a companion screensaver that is one of the few slideshow screen savers that allows you to see a different sets of pictures on each monitor in a multi-monitor setup, and with different options. (More details on this in ArtSaverApp's manual, or on the app's web page.)

Note that, by design, ArtSaverApp does not sport fancy visual effects, such as picture postcard, mosaic, or the like! It only offers still images, zoom in/out, and pan & zoom (a.k.a. Ken Burns effect). The goal of ArtSaver is to present images such that you can enjoy them in their full glory.
Note, also, that ArtSaverApp does *not* come with its own pictures; it assumes that you want to see *your* pictures.

Don't forget to go to ArtSaverApp's Preferences when you run it for the first time.

Some of the app's features (and the companion screensaver's):
• Can display the file name, full path, some embedded "EXIF" tags, and GPS location of the image currently being shown
• Keeps a persistent database of all the images found in the specified folder (including sub-folders). Thus, it can handle huge image databases (150k images are no problem), display images immediately when started, and, does not "exercise" the disk every time it gets invoked
• Handles large image files well (like 100+ MB)
• Keyboard controls at runtime (app only): go back to previously shown images, pause the slide show, reveal the current image in Finder, and more
• Many configuration options, such as duration of image, minimum image size, font size for info, and many more
• Can follow aliases (and symbolic links) during image search
• Images can be displayed in random or sequential order

Please note that ArtSaverApp CANNOT access the photos you keep in the Photos app of your Mac.

You can find the complete manual on ArtSaverApp's web page (and in the app, of course).

On the web page, there are further hints and tips, for instance, regarding older macOS versions or work-arounds for some obstacles.
