generate_image
Generate a YouTube thumbnail, channel banner, logo, product mockup or general image. Counts against the monthly image allowance (Pro 200, Premium 500, Ultimate 1,000 a month; extra images can be bought as image packs) and saves to the user's library. Make one image per request the user actually wants; never loop to produce dozens of variations unless they asked for that many. At most 100 images an hour go through this connector. Set image_type: it controls the shape of the result, and getting it wrong produces something the user cannot actually use. To feature one of the user's saved characters OR one of their made AI presenters in the image (a logo, banner or thumbnail with the presenter's face), pass character with their name and the face will match. PROFILE PICTURES: when the user wants a profile picture / channel icon / avatar circle of their presenter or character, use image_type profile_picture with character. That uses their ACTUAL image, cropped front-facing into a circle on white, with no regenerating, so it is never cartoon or animated. Never use logo for a picture of a person: logo is a flat graphic mark and turns faces into illustrations. To CREATE a reusable character rather than use one, use create_character instead. To make an AI PRESENTER or AVATAR (a talking on-screen host for videos), do NOT use this: use draw_presenter, which creates them in the right pose and leads to make_presenter.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| style | No | The art style. 3d_animated is the same look as the 3D Animated films (Pixar-style 3D): use it for every thumbnail, banner, logo and profile picture of a 3D animated, kids' 3D or Bible 3D animation channel or film, never 2d_cartoon. 2d_cartoon is a flat 2D cartoon. realistic is photo-real. Leave it out to let the prompt decide. | |
| prompt | Yes | What the image shows. Visual and specific. Include on-image text exactly as it should appear. Describe content only: the shape, aspect ratio and framing are handled automatically from image_type, so do not ask for dimensions here. | |
| character | No | Name of a saved character, a 3D cast character (list_3d_characters) or a ready AI presenter (list_presenters) to feature in the image, so the person in it is recognisably them; a first name is enough ("Cedric" for a presenter saved as Cedric). Use this to put a presenter on an ebook cover or product mockup. Optional. Must already exist: use list_characters, list_3d_characters or list_presenters to check. A 3D cast character is always made in the 3D animated look. | |
| image_type | No | profile_picture is a channel profile picture: with character it crops that presenter's or character's REAL image into a circle on white (no AI regeneration, the face is exactly theirs); without character it creates a square head-and-shoulders portrait, photographic unless the user asks for a style. youtube_thumbnail is 16:9 widescreen. youtube_banner is real 2560x1440 YouTube channel art with the whole design kept inside the area visible on every device (TV, desktop, phone). logo is a square graphic mark (text or symbol, flat shapes), not a picture of a person. mockup puts the product on a pure white background for a shop listing. general applies no shape rule. Defaults to general. |
