Create Beautiful Slideshows from Your Plex Photo Library

A photo sitting in a folder on your Plex server is a photo nobody sees. Slideshows change that. They turn a static archive into something alive -- a stream of memories playing on your TV during a family dinner, or scrolling on your phone while you wait for coffee. The problem is that Plex's built-in photo slideshow feature is limited in ways that make it frustrating for anything beyond the most basic use case.

This guide covers everything about creating a Plex photo slideshow: what the native Plex app offers, where it falls short, and how to build slideshows that span your entire photo collection, play on your TV in full resolution, and actually look beautiful.

Plex's Built-In Photo Slideshow

The Plex app includes a slideshow feature for photo libraries. Here is how it works and what it cannot do.

How to Start a Plex Slideshow

1. Open the Plex app on your device (iOS, Android, smart TV, or web).
2. Navigate to your photo library and open an album.
3. Tap any photo to view it full-screen.
4. Look for the slideshow or play button in the toolbar. The exact location varies by platform.
5. The slideshow begins, cycling through photos in the album automatically.

Limitations of the Native Slideshow

• Single-album only. The slideshow plays photos from one album at a time. You cannot create a slideshow that spans your entire Plex photo library or pulls from multiple albums. If your photos are organized into 200 folders by year and month, you get 200 separate slideshows, not one unified experience.
• No shuffle across albums. Shuffle only works within the current album. You cannot get a randomized "memories" experience that pulls from your whole collection.
• Limited timing controls. The display duration per photo is either fixed or has minimal adjustment options, depending on the client. There is no fine-grained control over pacing.
• On-device display only. The Plex app slideshow plays on the screen of the device running the app. It does not natively output to an external display via AirPlay in an optimized way.
• No curated selection. There is no way to mark favorites and then slideshow only your best photos. You get every photo in the album, including the blurry ones and the duplicates.

For a quick slideshow of a single vacation album, the built-in feature works. For anything more ambitious -- a whole-library slideshow on your living room TV, a curated highlight reel for a family gathering, or a continuously running photo display -- you need something more capable.

What Makes a Great Photo Slideshow

Before diving into solutions, it is worth defining what a great Plex photo slideshow actually looks like:

Cross-Album Playback

A slideshow should be able to pull photos from your entire library, not just one folder. Your memories do not live in silos, and your slideshow should not either. The best slideshows mix vacation shots from 2019 with birthday photos from 2023 and candid moments from last week.

Full-Resolution Display

If you are showing photos on a 4K TV, the slideshow should display photos at the TV's native resolution. Upscaled phone-resolution images look soft and washed out on a 55-inch screen. A proper slideshow fetches the original high-resolution file from your Plex server and renders it at full quality.

Clean Transitions

Each photo should fill the screen cleanly, with a simple hard cut to the next image. The focus should be on the photos themselves, not on distracting visual effects between them.

Controllable Pacing

Different situations call for different timing. A quick review of recent photos might use 3-second intervals. A background display during a dinner party works better at 8 to 10 seconds per photo. The slideshow should let you adjust this easily.

Curated Selection

Not every photo deserves slideshow time. The ability to mark favorites and then run a slideshow from only your best photos transforms the experience from "every photo I have ever taken" to "the highlights of my life."

Building a Better Plex Photo Slideshow with Phlix

Phlix was designed to address every limitation listed above. Here is how it handles slideshows differently from the native Plex app.

Whole-Library Slideshows

In Phlix, you can start a slideshow from any point in your chronological timeline. The slideshow plays forward through your photos in date order, crossing album boundaries automatically. Start from January 2020 and it will play through every photo you have, month by month, year by year, regardless of which folders they live in on your server.

Favorites-Only Slideshows

Mark photos as favorites while browsing, then switch to the favorites tab and start a slideshow. This gives you a curated highlight reel -- only the photos you have specifically selected. Perfect for showing off your best shots to guests without scrolling past every throwaway photo in your library.

On-Device and External Display

Phlix supports two slideshow modes. The on-device slideshow plays full-screen on your iPhone -- great for personal viewing. The external-display slideshow uses AirPlay 2 to send photos to your TV at full 4K resolution while your iPhone displays controls and a preview of upcoming photos. Your phone becomes a dedicated slideshow remote. For the complete technical walkthrough of the AirPlay setup, see our AirPlay slideshow guide.

Adjustable Timing

Set the display duration per photo from 3 seconds to 30 seconds. Change it on the fly during a slideshow without stopping playback. Running a slideshow as ambient background art? Use a longer interval. Reviewing photos quickly? Shorten it.

Shuffle

Enable shuffle to randomize the order across your entire collection. This creates a "random memories" experience similar to Apple Photos' "For You" feature, but sourced entirely from your self-hosted Plex library.

Tips for Better Plex Photo Slideshows

Regardless of which app you use, these tips will improve your slideshow quality:

Organize Photos by Date

Slideshows are most engaging when they flow chronologically. Make sure your photos have accurate EXIF date metadata so they sort correctly. If you have scanned old prints or downloaded images without proper dates, tools like ExifTool can help you set dates manually. For more on organizing your photo library, see our Plex photo library setup guide.

Pre-Generate Thumbnails

If your Plex server has not generated thumbnails for all your photos, the slideshow may pause or stutter as it waits for the server to create thumbnails on demand. Run a full library scan and let Plex complete all thumbnail generation before your first slideshow. Our guide on browsing large Plex photo libraries covers this process in detail.

Use a Wired Server Connection

Full-resolution photos can be 5 to 15 MB each. If your Plex server is on Wi-Fi, loading each photo for the slideshow may take noticeably longer than on a wired Ethernet connection. A wired server ensures each photo loads fast enough for smooth transitions.

Curate Before You Present

Spend 10 minutes marking favorites before a family event. Browse through your timeline, long-press the best shots, and build a favorites collection. When it is time to show photos, start a favorites-only slideshow instead of playing through everything. The difference in quality is dramatic -- your audience sees only your best memories, not the five nearly identical photos you took trying to get everyone's eyes open.

Plex Photo Slideshow on Your TV

The most impactful way to experience a photo slideshow is on a large screen. A 55-inch or 65-inch TV turns your photos into an experience that a phone screen simply cannot match. There are two approaches to getting your Plex photo slideshow onto your TV:

• Screen mirroring. Mirror your phone's screen to the TV via AirPlay. Quick and easy, but the TV shows your phone interface (navigation bars, status bar, notifications) along with the photos. Resolution is limited to your phone's screen resolution, not the TV's native resolution.
• Extended display (Phlix). Phlix outputs photos to the TV as a true second screen. The TV shows only the photo, edge to edge, at up to 4K resolution. Your phone shows slideshow controls independently. This is the approach that makes photos look their best on a big screen.

For a detailed comparison of these approaches and setup instructions, see our guide to streaming Plex photos to your TV with AirPlay.

The Bottom Line

Your Plex photo library is a treasure. A good slideshow is how you actually enjoy it. The native Plex slideshow gets you started, but for whole-library playback, curated favorites, and full-resolution TV display, a dedicated Plex photo slideshow tool makes the difference between a feature that technically exists and an experience you will actually use.
