Thumbnail Skill
This skill enables generation of high-performing thumbnails and cover images optimized for click-through rate (CTR). Thumbnails are designed to spark curiosity, complement titles, and compel viewers to click.
Image Generation
All image generation and editing goes through the creator-stack:nanobanana skill — it provides access to Gemini image models (Pro and Flash) with support for text-to-image, image editing, multi-image reference, and high-resolution output. Invoke it before generating or editing any thumbnail.
Model Selection for Thumbnails
- Pro (default) — Use for final production thumbnails. Supports 2K/4K resolution, up to 14 reference images, and thinking mode for better composition.
- Flash — Use for rapid exploration and draft concepts. Faster and cheaper, good for iterating on ideas before committing to a final version.
Rule of thumb: Use Flash for exploration batches (generate 5-10 variations), then Pro for the final production image.
Essential References
Read both of these before generating any thumbnail — they contain the design patterns and prompting techniques that make the difference between a generic image and a high-CTR thumbnail:
