Message → Generate Thumbnail
AI-generatedSummary
Parse an image attachment object and return a thumbnail result. The implementation currently uses the attachment’s original URL as the thumbnail rather than resizing or uploading a new image.
Inputs
- Image Data (required) — JSON string describing the image attachment, for example with
contentTypeandcontent. The operation parses this value as attachment data. - Max Width — Maximum thumbnail width in pixels; defaults to 200 (UI range: 50–1000).
- Max Height — Maximum thumbnail height in pixels; defaults to 200 (UI range: 50–1000).
Output shape
A single output item containing the thumbnail result.
The helper returns a placeholder thumbnail URL, using the original image URL; it does not perform image resizing or upload a generated thumbnail. The supplied source pack omits the operation body, so the exact output field names are not shown.
