What are card news thumbnail prompts?
Card news thumbnail prompts are instructions for designing the opening image of an information post so readers understand its topic before opening the full sequence. Instead of squeezing every detail into one frame, the prompt defines a short headline, one key number or phrase, a hero image, contrast, and a clear title zone. With GPT Image 2, an education guide, travel tip, interview, product story, or brand update can become a coherent cover concept that leads into the rest of the cards.
What content can use this format?
Use it for policy explainers, news summaries, lessons, event notices, product information, interviews, travel guides, and data-led posts. Reduce the subject to one promise or question. A person-focused post can combine a face with a short name or role, while a statistics post can make one important number the visual anchor. The thumbnail should invite a click without trying to reproduce the entire article.
The information hierarchy
Define the audience and the question the post answers. Then rank the headline, subtitle, hero image, number, and icons. Keep a safe margin around the edges and specify the brand palette and contrast between background and type. A shared cover rule helps a channel look consistent across different subjects. If the headline is long, shorten it rather than filling the frame with tiny copy.
Making it readable on mobile
Feeds display thumbnails at a small size, so remove busy backgrounds and minor decoration. One strong headline, one recognizable image, and a limited palette usually communicate faster than a crowded collage. Always verify generated words, dates, units, and numbers, then correct alignment and spelling in an editing tool before publishing.
A practical prompt formula
Describe the topic, audience, short headline, hero image, palette, layout, and publishing ratio in that order. For a travel guide, request a destination landmark, a large numbered title, a small map icon, and a clean vertical cover with generous space.
