Slideshow Production
Class Reunion Photo Slideshow: A Production Guide
The slideshow is the emotional centerpiece of a reunion. Built well, it triggers laughter, tears, and a 30-minute energy boost. Built badly — too long, wrong music, blurry photos, no flow — it kills the post-dinner momentum just before the dance floor opens. This guide walks through the production from photo collection to projection.
The structure of a great reunion slideshow
A 10-minute slideshow with 100-120 photos has a clear arc:
- Opener (0:00-1:00): 10-12 photos from senior year. Yearbook portraits in a fast montage to set the era.
- School memories (1:00-3:30): 25-30 photos. Sports, prom, homecoming, plays, dances, group shots in the hallway.
- Friendships (3:30-5:30): 20-25 candid shots of friend groups, parties, road trips, sleepovers — the stuff that wasn't in the yearbook but happened in the parking lot.
- Where we went (5:30-8:00): 25-30 current photos — classmates' weddings, kids, travels, careers, milestones. The "we made it" section.
- Memorial moment (8:00-8:30): 30-second pause with names and photos of deceased classmates. Music drops to silence or a single piano note.
- Group photos through the years (8:30-9:30): 10-15 photos of class reunions past, if you have them.
- Closer (9:30-10:00): 5-6 portraits of classmates in the room today. End on a group shot from this reunion's arrival hour if you can.
The pacing rule
How to collect photos from classmates
Three calls for photos, with progressively more urgency:
Call 1: at ticket purchase (4 months out)
RSVP form includes an upload button: "Add your favorite senior-year photo for the slideshow (optional but appreciated)." About 30-40% of classmates upload here.
Call 2: dedicated email (1 month out)
Subject: "Send us your old photos for the slideshow." One link, one CTA, deadline in subject line. Specific asks help: "old prom photos, sports team shots, candid hallway shots, anything from the senior trip."
Call 3: final reminder (1 week out)
"Last call — slideshow uploads close Friday." Drives the final 15-20% of submissions.
Collection tools that work
- Reunly upload page — auto-organized, no committee curation needed.
- Google Drive folder — works fine; requires a committee member to download and rename files.
- Dropbox shared link — same as Google Drive.
- Never use email attachments — photos get lost in inboxes and the committee member spends hours hunting them down.
Supplementing with yearbook photos
If classmate uploads come up short, the yearbook is your backup. Scan or photograph these pages at high resolution:
- Senior portraits page (whole class as a montage)
- Sports team photos
- Drama productions and band photos
- Homecoming, prom, dance pages
- Clubs and organizations
- Candid shots scattered throughout
- Senior trip page if it exists
Yearbook scans alone can fuel an entire slideshow. Combined with even 20-30 classmate uploads, you have plenty.
Building the slideshow
Software options
- iMovie (free, Mac): drag photos into a timeline, set duration per photo, add a music track. Sufficient for 95% of reunions.
- CapCut (free, all platforms): easier learning curve than iMovie.
- Google Slides set to auto-advance: works in a pinch.
- Animoto / Smilebox ($15-30 paid): drag-and-drop with built-in templates. Good if no committee member knows iMovie.
- Reunly slideshow builder: auto-builds the slideshow from classmate uploads with timing pre-set.
Music selection
One song, instrumental or low-vocal, from your graduating era or a timeless emotional track. Common picks:
- Coldplay — Clocks (instrumental ok with vocals)
- Bon Iver — Holocene
- Explosions in the Sky — Your Hand in Mine
- The Cinematic Orchestra — To Build a Home (slow build, emotional)
- Sigur Rós — Sæglópur
- Era-appropriate instrumental: Sade, Enya, Vangelis Chariots of Fire
Avoid songs with specific personal associations (wedding songs, funeral songs) — they derail viewing for anyone who has that association.
Photo quality fixes
- Crop loose photos to face level — wide shots lose impact on a projector.
- Auto-enhance with iPhone Photos or Google Photos — quick brightness/color fixes.
- Skip blurry photos. Better to have 80 great photos than 120 mixed-quality.
Presenting the slideshow without disaster
Pre-event technical check
- Visit the venue with the laptop the week before. Test the actual projector or screen.
- Bring your own HDMI cable + adapter (USB-C to HDMI, mini-HDMI to HDMI). Venues rarely have the right one for your laptop.
- Bring a backup on a USB stick. If the laptop fails, the venue can usually run the file off a stick.
- Test the audio. Confirm the slideshow audio runs through the venue's speakers, not the laptop speakers. The difference is huge.
- Set the laptop to never sleep during the event. Disable screen savers.
Day-of run
One committee member is the slideshow runner. They're standing by the laptop at 7:55pm. The host signals; runner clicks play. Stays at the laptop for the full 10 minutes in case of glitches.
The number-one slideshow disaster
After the event — sharing the slideshow
The day after, upload the slideshow file to a shared link (Google Drive, YouTube unlisted, or Vimeo). Include the link in the thank-you email. Classmates rewatch it and share with classmates who couldn't attend.
Archive the photo source folder. The next reunion committee will thank you when they don't have to recollect every photo from scratch.

How long should the slideshow be?
8-10 minutes maximum. After 10 minutes, audience attention drops sharply and the segment loses its emotional peak. If you have 200+ photos, the slideshow runs too slow at 4 seconds per photo or too fast at 3 — either way, cut the photo count, not the timing.
How do we collect photos from classmates?
Three calls for photos: (1) at ticket purchase, with a clear upload button; (2) one month before the event with a specific deadline ('uploads close September 15'); (3) one week out as a final reminder. Use a single upload tool — Reunly, Google Drive folder, or a dedicated upload form — never email attachments (you'll lose photos in inboxes).
What music should play under the slideshow?
A single instrumental or low-vocal song from your graduating era. Vocals compete with the photos for attention. Common picks: Coldplay 'Clocks', Bon Iver 'Holocene', Explosions in the Sky, instrumental versions of era-defining songs. Avoid songs with strong emotional associations (someone's wedding song, a funeral song) — those derail the viewing.
When should we play the slideshow during the evening?
8:00-8:10pm, between dinner and the dance floor opening. Cocktail-hour slideshow play is okay but lower impact — people are talking and not watching. The post-dinner slot is the emotional peak of the night and the slideshow is what owns that slot.
Should the slideshow have captions?
Sparingly. Caption only the photos that aren't self-explanatory (a candid group shot with names, a senior trip photo with the year). Captions on every photo crowds the slide and slows the pacing.
What about photos of classmates who have passed away?
Include them in the slideshow naturally, but also do a separate dedicated memorial moment (60-90 seconds) before the slideshow with just the deceased classmates' photos and names. Don't put a heavy memorial in the middle of an upbeat slideshow — separate the tones.
What if not many classmates send in photos?
Supplement from the yearbook. Scan senior portraits, prom photos, sports team shots, drama productions, club photos. The yearbook alone can fuel a 10-minute slideshow if classmate uploads come up short.
