$addThumbnail[] — Visual Thumbnail

$addThumbnail[] inserts a thumbnail image in a container section. This function adds a standalone image component — distinct from the traditional embed thumbnail set by $thumbnail[].

$addThumbnail[url;(description);(spoiler)]

Parameters

Parameter	Required	Default	Description
url	Yes	—	URL of the image (must be a valid URL).
description	No	—	Alternative text for accessibility.
spoiler	No	no	yes to hide the image.

Return value

Adds the thumbnail image to the current section of the container. The image is rendered in a small format.

Notes

• Must be used in a section ($addSection) inside a container ($addContainer).
• Do not confuse this with $thumbnail[] which defines the thumbnail of a classic embed.
• The URL must point to a publicly accessible image (PNG, JPEG, GIF, WebP).
• For a gallery of multiple images, use $addMediaGallery[].
