ILS Platform Guide

ILS & Platform Photo Requirements for Property Managers

Exact specs, dimensions, and best practices for every major rental listing platform. Updated for 2026.

Why This Matters

ILS Platforms Drive Renter Discovery

86% of renters use Internet Listing Services during their apartment search, and the average renter visits 4 platforms before making a decision. The first 7 days of a listing are critical for visibility. Listings with 20+ photos see up to 9x more engagement than those with fewer images. Getting your photos right on every platform is not optional — it directly affects vacancy duration and lease-up speed.

How It Affects Visibility

Zillow's algorithm auto-selects your primary photo for search results. You cannot manually choose which image appears first — the system picks based on its own criteria. Kitchen and living room photos tend to perform best as primary images.

At least 1 photo is required to publish a listing, but listings with 20+ photos generate significantly more renter engagement. Higher resolution images display better on any device, so shoot well above the 330×220 minimum.


Pro Tips

  • Use kitchen or living room photos as your primary image — these perform best when Zillow's algorithm auto-selects
  • Upload at least 1 photo (required), but aim for 20+ to maximize listing engagement
  • Stick to JPG, GIF, PNG, or TIF formats — all are accepted
  • Keep file sizes under 10MB per image
  • Shoot at a resolution well above the 330x220 minimum — higher quality images display better on any device
  • Photograph every unit type, common areas, and exterior views to give renters a complete picture

How It Affects Ranking

Apartments.com rewards listing completeness. Complete all data fields alongside your photos to maximize your listing's position. The platform favors properties with comprehensive photo galleries and complete amenity information.

Unit-level photos are preferred over generic model shots. Amenity-specific images (pool, gym, laundry, parking) drive significant prospect engagement. Properties with 25–35 high-quality images perform best on this platform.


Pro Tips

  • Upload 25-35 high-resolution images for maximum listing performance
  • Complete all data fields alongside photos — Apartments.com rewards listing completeness
  • Include amenity-specific photos (pool, gym, laundry, parking) — these drive prospect engagement
  • Use unit-level photos when possible rather than generic stock or model unit images
  • Listings with 20+ photos see up to 9x more engagement than those with fewer
  • Show different floor plan types so prospects can visualize their specific unit

Also Worth Covering

Additional Platforms

Rent.com

Part of the RentPath network, Rent.com shares listing data across multiple sites. High-quality photos uploaded once can appear across the entire RentPath ecosystem.

  • Part of RentPath network
  • High-res images recommended
  • Video tour support

Craigslist

Basic but still relevant for many markets. Craigslist listings with clear, well-lit photos stand out dramatically against the low-quality competition typical on this platform.

  • Basic photo uploads (~5MB limit)
  • Still drives significant local traffic
  • Quality photos stand out here

Facebook Marketplace

Casual format, but real photos perform far better than stock images. Facebook's audience expects authentic, high-quality images that show the actual unit.

  • Real photos outperform stock images
  • Casual but growing rental channel
  • 1200×630px recommended for best display
