Upload guide

    Upload Guidelines

    Use this page as the uploader-facing contract for file requirements, metadata quality, and the split between public notes and private screening comments.

    File requirements

    These checks are enforced by the upload flow before the file reaches screening.

    JPEG only
    Minimum file size: 250 KB
    Maximum file size: 20 MB
    Maximum width: 1280 px
    Minimum long edge: 1024 px
    Minimum short edge: 576 px
    Aspect ratios from 4:3 to 3:2, plus 16:9

    Aircraft uploads

    Aircraft photos and aviation subjects where aircraft identity matters.

    Required

    • Airport
    • Photo date
    • Primary category
    • Registration or aircraft model
    Registration is preferred when known, but registration or aircraft model is enough to pass the minimum metadata requirement.

    Airport uploads

    Airport overviews, terminals, towers, spotting locations and airfield context.

    Required

    • Airport
    • Photo date
    • Airport view / primary category
    Airport uploads do not require registration, aircraft model or serial number. Use a public note when the image needs context.

    Metadata and airport selection

    Auto-fill helps, but the uploader remains responsible for accuracy.

    • Use Auto-fill first when you know the registration and/or airport code.
    • Check every auto-filled field manually before submitting.
    • Use the real airport catalogue when possible.
    • Manual code fallback and special locations exist for edge cases, not as the default path.
    • Exact dates are expected for digital photos whenever possible.

    Notes and visibility

    Public information and private screening context are intentionally split.

    Photo note

    Public. Shown with the photo. Use it for short editorial context.

    Comment to screener

    Private. Visible only to the screening team while relevant. Not the place to ask for editing advice.

    Common rejection triggers

    Passing upload validation does not guarantee acceptance during screening.

    Soft or blurry image
    Bad centering or weak composition
    Horizon problems
    Dust spots
    Poor exposure
    Duplicate or too similar submission
    Manipulated image
    Bad or incomplete information

    Appeals

    Appeals exist for incorrect decisions, not for editing support.

    Use an appeal only when you believe the rejection was incorrect. Do not use appeals to ask how to edit a file or how to make it acceptable.

    The current business rule is intentionally strict: a photo gets one meaningful appeal path. If an appeal is accepted, the photo returns to screening. If it is rejected again after that, it does not enter a new appeal loop.
