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
