user: Explain Properties in complete detail according to the official Blender documentation.

assistant: The current import settings can be saved as an [Operator Preset](../../interface/window_system/tabs_panels.html#ui-presets).

### Options

Relative Paths
:   Stores the image file path relative to the currently open blend-file.
    See [Relative Paths](../../files/blend/open_save.html#files-blend-relative-paths).

Force Reload
:   Reloads the image file if it already exists as an image data-block.

Detect Image Sequences
:   Imports sequentially numbered images as an animated
    [image sequence](../../editors/image/image_settings.html#image-sequence) instead of separate planes.
    The frame range of the sequence is automatically set (which can be adjusted later).

### Material

A material is automatically created for the plane to display the imported image. The following shader options are
available:

Shader
:   The type of node shader to use.

    Principled:
    :   Uses a [Principled BSDF](../../render/shader_nodes/shader/principled.html) shader.
        The imported image is linked to the *Base Color* input.

    Shadeless:
    :   Creates a material that does not respond to lighting.
        Uses a mix of Diffuse and Emission shaders controlled by a Light Path node.

    Emission:
    :   Similar to *Principled*, but links the image texture to the *Emission* input instead of *Base Color*.

        Emission Strength
        :   Adjusts the intensity of emission.

Render Method
:   Controls the blending and the compatibility with certain features.
    See [Material Settings](../../render/eevee/material_settings.html#bpy-types-material-surface-render-method) for more information.

    Dithered:
    :   Allows for grayscale hashed transparency, and compatible with render passes and raytracing.
        Also know as deferred rendering.

        When using *Dithered* render method, the materials are rendered in layers.
        Each layer can only transmit (e.g. refract) light emitted from previous layers.
        If no intersection with the layers below exists, the transmissive BSDFs will fallback to light probes.

    Blended:
    :   Allows the colored transparency, but incompatible with render passes and raytracing.
        Also known as forward rendering.

        Show Backface
        :   Displays the backface of transparent areas.

Backface Culling
:   Hides the plane’s backface.

Overwrite Material
:   If an imported image shares a name with an existing material, Blender appends a number to differentiate it.
    Enabling this option forces the new material to overwrite the existing one.

### Texture

Interpolation
:   Defines how the image is scaled when displayed on the plane.

Extension
:   Determines how the image is extrapolated beyond its original boundaries.

Alpha
:   Enables transparency using the image’s alpha channel.

Auto Refresh
:   Automatically updates images in the viewport when the frame changes.

### Transform

Imported planes are positioned at the 3D Cursor’s location. Multiple planes can be offset using the *Offset Planes*
option.

Size Mode
:   Determines how the plane’s size is set:

    Absolute:
    :   The plane’s height is explicitly defined in *Height*, with width adjusted to maintain aspect ratio.
        Example: An image of 800 × 600 pixels with a height of 1 m results in a width of 1.33 m.

        Height
        :   Sets the height of the plane.

    Scale to Camera Frame:
    :   The plane is sized relative to the active camera.

        Scale
        :   Method to scale the plane with the camera frame.

            Fit:
            :   Scales the plane to fit inside the camera frame while preserving aspect ratio.

            Fill:
            :   Scales the plane to fill the entire camera frame, possibly cropping some areas.

    Pixels per Inch:
    :   Determines the plane’s size using the *Definition* value, measured in pixels per inch.
        Example: With a 600 DPI setting, an 800 × 600 px image results in a plane size of ~0.0339 × 0.0254 m.

        Definition
        :   Sets the number of pixels per inch.

    Pixels per Blender Unit:
    :   Uses *Definition* to define pixels per Blender Unit.
        Example: With a setting of 600, an 800 × 600 px image results in a plane size of 1.33 × 1 BU.

        Definition
        :   Sets pixels per Blender Unit.

Align
:   Specifies the plane’s rotation upon import.

    Z- (Down), Y-, X-, Z+ (Up), Y+, X+:
    :   Rotates the plane to align with the selected axis.

    Face Camera:
    :   Directly faces the camera.

    Camera’s Main Axis:
    :   Aligns the plane to a major axis facing the camera view direction.

Track Camera Face Camera Camera’s Main Axis
:   Adds a [Locked Track](../../animation/constraints/tracking/locked_track.html) constraint,
    ensuring the plane always faces the camera.

Offset Planes
:   Offsets multiple planes instead of stacking them.

Offset Direction
:   Specifies the axis along which multiple planes are spaced.

Distance
:   Defines the spacing between planes.
