On a saved meal click Generate Meal Image with AI above the main image box. Fill or accept Dish Name, Ingredients Visible, Cuisine Style, Lighting Style, Camera Angle, Dishware, Background, Background Color and Mood/Style (quality is fixed to ultra realistic and the prompt forbids any text or logos). Choose Save Image To: Main Image (or Main Image (replace)), New (add to gallery), or replace a specific Secondary #n. Click Generate Image and allow 30-60 seconds; the image is saved immediately (no need to click Save) and the preview updates.

If the gallery already holds nine extra images you get "Gallery is full (max 9 additional images)" - replace an existing slot instead.
