Promo images

Every promo has an image so it's ready to share.

AI-generated images (Pro & Unlimited)

On Pro and Unlimited, click Generate image on any promo and SlingAgent creates a unique image from its prompt — no design work needed. Click Regenerate any time you want a different take. (Generating on demand keeps you in control of when images are created.)

Upload your own

Don't like the generated image? Click Upload on any promo to use your own (PNG, JPG, or WebP, up to 4 MB). Your upload replaces the current image right away — available on every plan.

Defaults

Before an AI image exists, a promo uses the link's own image (for example a book cover or the page's preview image), so it always has something to show.
