Promo images

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

AI-generated images (Pro)

On the Pro plan, SlingAgent automatically generates a unique image for each promo from its image prompt — no design work needed. Open a promo and click Regenerate any time you want a different take.

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.
