Which crop to use depends on your MLS. Canopy MLS, for example, stores images at 2048×1536 (4:3).

Why MLS photo rules vary

Rules vary by MLS and state. Two examples:

Canopy MLS (Matrix)

  • Stores images at 2048×1536 (4:3) and recommends that as the minimum.
  • Accepts up to 3000×3000.
  • JPEG only (.jpg/.jpeg), max 6 MB per image.
  • Up to 48 photos per listing.
  • Processes in sRGB.
  • Other ratios get white space added and may be flagged as smaller than the recommended minimum, though Canopy says they can still be used.

CRMLS

Your MLS may differ on any of these points, so read its current photo rules before you upload. For a longer guide, see MLS photo requirements.

Branding and watermarks

Rules vary by MLS and state. CRMLS, for example, bans branding in listing media.

In Lumo, free exports carry a small "Enhanced by Lumo" badge. Lumo Pro adds the option to turn off the "Enhanced by Lumo" badge, and agent branding (headshot, logo, contact info) on exports.

Before you upload, check each photo against your MLS's branding rule: look for logos, contact info, badges and watermarks.

Disclosing AI edits

Lumo uses AI. Its enhancement is designed to keep the room's size and layout, walls, windows and doors, materials and colors, fixtures and existing furniture as they are, but results must be reviewed. Lumo tells agents to review every photo against the property and follow their MLS's rules on edited and staged photos.

Staged photos (and exteriors) export with a "Virtually Staged" label by default; the app warns before you turn the label off. Because exteriors get a replaced sky, exterior exports carry the "Virtually Staged" label too.

Disclosure rules vary by MLS and state. For example:

  • California AB 723 (Bus. & Prof. Code §10140.8), in effect January 1, 2026: licensees must clearly disclose images digitally altered in a way that changes the appearance of the property (including AI) and make the original, unaltered image available. Source: California DRE advisory on AI in real estate.
  • CRMLS digitally altered image rules: a label such as "digitally altered" or "virtually staged", and the original shown immediately before or after. Source: CRMLS digitally altered images FAQs.
  • NorthstarMLS guidelines for virtual staging and AI-enhanced listing photos. Source: NorthstarMLS guidelines.
  • NAR Code of Ethics (2026): Article 12 and Standard of Practice 12-10 (no misleading images). Source: NAR 2026 Code of Ethics and Standards of Practice.
